oh man, its mostly the alcohol that is causing your problems. trust, i have been there.
since ethanol is a depressant your brain gets used to the constant inhibition. add up the hours in a day that you have alcohol in your system. if you included the hours that you are sleeping (because you are probably most drunk right before you go to sleep), it might add up to half or more of your day. of course your brain gets used to this constant inhibition.
the rest of time you are going through mild withdraws.
also, you probably get hypoglycemic from drinking and that fucks you up hormonally, which can add to the anxiety. plus, nobody sleeps well drunk so your are tired all day. i know exactly how this feels to live it every day for months.
in order to control myself, i usually decide how much i will drink a night and only buy that amount. lately i have been restricting myself to one 24 ounce can of beer a night. i cant by 12 packs otherwise i would have 6-10 beers every night.
also, kava is nice to have. it gives a little relaxation similar to alcohol but not as addicting.
