Alcohol used to be fun in college, but now i can't seem to get out of this funk.

Depressant: Alcohol is a central nervous system depressant. It eventually lowers your mood. The "buzz" that people feel when intoxicated is related to the lowering of inhibitions due to the depressant effect on the brain. Chronic alcoholics often need larger amounts of alcohol to achieve this effect which often lasts for a shorter period. This creates a vicious cycle and sustained abuse.

Time to stop: If you are having this problem, it is time to quit. I would recommend starting a good diet and exercise program. Alcoholics anonymous is a good start. Also, daily multivitamins, omega three fatty acids in the form of fish oil help. Also, have a complete physical.
