What to do If
...you need more clothes: finding clothing such as what you are used to at home is not that easy. There are a few shops that import items from Europe but they tend to be limited and expensive.
The markets sell imported clothing, often from China, donated items or items that are made locally. As a better alternative, have your own clothes made. It's easy to get fabric in just about any market, especially in Serrekunda and Banjul. 
Pick 6 meters up for about D150 and go to one of the many tailors available (perhaps ask for a recommended one from a fellow volunteer/ex-pat).
If you show the tailor what you want either by an actual example, showing him a picture in a magazine or drawing it out, he will make what ever you want within less then a week for D150 or so.
...you are tired of eating tapalapa and spam: get creative and start cooking. There are always little shacks on the sides of the streets selling fresh fruit, vegetables, and eggs. Why not make a salad with tomatoes, lettuce, cucumbers, carrots, green onion, a bit of lime juice and olive oil?
Or make an omelet, a curry, humus with pita bread, fruit salad, etc. with many of the ingredients available in the grocery stores for relatively cheap prices.
...you are tired of being hassled by people asking your for money and calling you "toubab": relax. You are a visitor to The Gambia and thus are looked upon as rich and full of opportunities. Being called a 'toubab' is normal and not meant in any sort of negative way.
Also, learn to say no in a firm but polite way when being asked for money and choose carefully as to who you will give money to or help sponsor if you do decide to.
...you have had enough of the heat, the power (if you have any at all) isn't on so the fan isn't working, there are no cold drinks available, and all you can do is sit there and sweat: Try going outside and sitting in the shade just as the locals do, as it will likely be cooler outside with a nice breeze from the ocean (if you are near the coast that is) than inside your home.
Take it easy and have a nap just as locals do too in the mid-afternoon.
Get a locally made fan, drink plenty of water, and think about how cold it probably is back at home. If you are lucky enough to be near the ocean go for a swim, and some of the hotels even offer a free dip in their pool if you purchase a drink or lunch (Safari Garden Hotel has a small but clean pool for use by volunteers).
...you find yourself drinking and/or smoking a lot more than you used to back at home: this has happened to many volunteers, probably due to a combination of stress, cheap prices of alcohol and cigarettes, and going out a lot more.
Obviously try not to drink and smoke too much. Instead, keep yourself busy and remain physically active.
Join a local gym or running club (yes, both of these exist in the Kombos area), go swimming, play soccer (football) with the neighbours, practice yoga and pilates or even just go for a daily walk along the beach or nature parks with friends.
...you are bored: try taking up a hobby such as:
writing (many volunteers keep an online blog/journal and some have even written novels about their life in The Gambia or elsewhere)
reading (various book stores exist in The Gambia and if you are a VSO volunteer the office has a good little library for you)
photography (The Gambia is very picturesque, just be sure not to take photos of Gambians unless you have asked permission)
bird-watching (ok, this may not sound interesting but give it a try! Get a book on local birds and a list and see how many you can spot during your seemingly endless time here...)
painting (water-colours and sketch-books can be found sometimes in the Kombos area)
talk to the locals (some amazing stories can be heard by the elders and young alike)
go traveling (even the compound next door can provide an interesting experience or set off on a trip to the neighbouring countries Senegal or Mali)
do touristy things (visit the crocodile pools, go on river trips, fish, etc.)
learn a new language (bring audio files and/or books with you from home or learn a local language). The Alliance Francais in Kanifing on Kairaba Avenue offers French lessons at very reasonable prices. There's a nice cheap restaurant on-site as well.
learn how to play the djembe (local drum), lessons can be given by many locals
visit other volunteers!
...you need intellectual stimulation: If you find that you are lacking some decent conversations about politics, philosophy, etc. try the following:
> Go to Timbooktoo, the bookstore in Fajara. Even just browsing the great books available there is enough and although the prices are high, they are no higher than what you would pay at home in most cases.
> Go to an Internet Cafe (if you don't have access to the Internet at home or work) and read the news online (BBC, CBC, NY Times, etc.).
> Get a local paper and get an international paper (The Guardian). Keep clippings from the local paper as an interesting memory...
> Find the Economist and Newsweek at some of the larger grocery stores. The cost is about D125 but well worth it.
> Go to The Kora Bar & Restaurant, The Green Mamba, Come Inn, The Blue Bar, and other bars/restaurants to find other volunteers and ex-pats to have discussions with.
Possible issues for volunteers
Some Gambians may expect African-American volunteers to learn the local languages and adapt to Gambian culture quicker than other volunteers.
This is also the case for African volunteers that are not from The Gambia. African-Americans may also be mistaken for a Gambian and/or African and may experience impatience on the part of Gambians when they do not demonstrate expected behaviour.
Asian, Arab, and Hispanic volunteers may be called such things as "chinese, ching chong, lebanese, indian," etc. by some Gambians, mostly children, just as many tourists and Caucasian volunteers are called "toubab."
This name calling is not necessarily meant in a negative way however, and perhaps lends an opportunity to educate the name caller about the diversity of the world outside of The Gambia.
Gay, lesbian, or bisexual volunteers are to be aware that most people in The Gambia, especially the older generation, are very conservative in their attitudes towards non-heterosexual orientation.
In fact, it has been officially announced in May of 2008 by the President of The Gambia that any non-heterosexual acts are strictly illegal and the person(s) involved will be deported and/or jailed or worse.
Any public display of affection is generally frowned upon at is it, whatever your orientation.
