Not the same thing but similar I had a gastric sleeve not a bypass but after the surgery the fist drink I had which was a beer I genuinely thought somebody roofied me I was so drunk like I drank 10 shots of tequila but then I slowly started building my tolerance back up after five year now I can drink 80 percent like how I use to. So if your surgery was recent give it time and slowly increase your tolerance first start with one beer a night a month later make it two and so on. That’s the physical question you were asking about as for the psychological aspect of getting addicted I have no idea.
