40YO Male, drink on weekends, normally Friday and Saturday nights. 8-10 beers and maybe 1-2 shots. Started feeling like an eternal battle from hell is going on in my head on Mondays. Sooo I tried only drinking on Friday, and that battle occurred on Sunday. Went a weekend without drinking and no battle. If I drink on day 1, day 2 I am hungover, but not in a bad way. No headache or any neg symptoms, just a slight euphoric state all day. I work out hard 6 days a week and drink a lot of coffee and water. I eat very healthy 5/7 days a week. I just cant take the day 3 depression and anxiety. I know the simple answer is don't drink. What causes this? Is it the euphoria is gone and my body is readjusting to normal? All of this only started about 4 months ago. Thanks for any assistance.
