"Could someone please give me advice and help me to stop thinking such irrational thoughts?"
id suggest to start by not rationalizing that " limiting my alcohol intake " is part of the recovery process.
then look into a recovery plan/program.
I still find it amazing that since I got sober-100% abstinent, that I haven't had to wake up/pass in the morning after full of fear and anxiety of what my actions might have been the night before.
