I can get drunk around my friends and have a good night, but as soon as I try and drink alcohol around my girlfriend I feel really ill, end up being sick and feeling hungover te next day even though I only drink a pint or two. I feel like it's hindering our relationship as she often wants me to drink and have a good time with her, like I do when I'm just with my friends. I'd just like to know what's wrong or why I can't drink around her like I can everyone else before it causes an argument in our relationship.
