My hangovers are weird and idk if its normal

I would first like to clarify that I’m not looking for medical advice, so I’m not breaking any rules. I just want to know if this is normal or not. I am 20 and I only drink socially, which is fairly often. Whenever I drink past the point of tipsy, I get these terrible stomach cramps and a nausea that lasts all night and won’t let me sleep. They only happen when I am laying or sitting down. If I’m standing up they are not that bad, sometimes not even noticeable. The weird part is that I don’t even throw up 95% of the time. None of my friends experience anything similar. Either they throw up instantly or they’re able to sleep through the night and throw up in the morning. Why am I going through 8 hours of agony just for nothing to happen in the end? Is this normal
