What should I do if I want to drink so badly?
Do you have a drinking problem?
Yes, but I'm trying to quit.
If you have a drinking problem you have to stop drinking altogether. If you're having urges to keep drinking you should join an AA meeting, they can help you stay sober.
Alcohol gives me power.
Alcohol does not give you power, it just blocks you from making logical and rational decisions. You should fight the deisre to drink if you have drinking problems. AA meetings are also beneficial to those with alcohol addictions.
