Oh, the allergy thing was definitely a lie because she was just too embarrassed or insecure to say she didn’t want to drink, for whatever reason. Her whole persona with Aslan was homebody/won’t drink/bed early/didn’t go to clubs or bars/maybe one friend, etc. Tbh it was kind of your classic ‘depressed, anxious, and codependent but hide all that by saying you just love staying home and can’t drink’ thing.
It’s reminiscent of young people in university or whatever who don’t want to do the drunken party thing so they think of some elaborate reason like ‘oh it’s so crazy I’m ALLERGIC to alcohol’, because they think they need a specific reason to decline a drink and then no one will question them more or pressure them to have one.
The funny thing is she’s also now acting like a 19 year old who just rebelled and started drinking by constantly telling everyone every single time she drinks and making sure everyone knows she’s feeling hungover/‘kinda FRAGILE this morning you guys’ because she’s being the cool girl she never was but she doesn’t get that she’s way overdone it at this point and no 32 year old would be going on about it this much? Also how she always narrates when she starts feeling drunk, like ‘I’m starting to feel really happy now’, it‘s SO cringey and weird. She gets so much validation by telling people she’s having a drink.
(Also she did ‘answer’ this by claiming that she thought her hangovers were an allergic reaction so she just thought she was allergic. Yeah, sure, that makes so much sense).
