Just for some context, I used to be able to drink a lott when i was younger and pretty recently. but unfortunately nowadays every time i drink, even in very small quantities, it always starts with rlly bad indigestion and acid reflux, then nausea, then just anxiety that lasts thru out the night. All this is alongside the typical effects from alcohol, the euphoria and confidence. I’m probably going to stop drinking, but i’m at uni and hate clubbing and partying, ngl tho drinking helps with my ability to do those things and meet ppl (i got mild social anxiety). Also not to condone further use, but anyone have these problems and solved them? And i guess the main question is why this could be?
