My roommate is turning into a demon, is it her allergy meds?

My roommate (22, F) recently started taking her allergies pills daily instead of as needed. She’s on Claritin and Montelukast. We’re in college so we drink pretty frequently. Lately, whenever she drinks, she stays up crazy late (like 9am). She’s been banging on random stuff, coming into my room randomly at 7am, and talking absolute nonsense. She has no recollection the next day, and whenever we stop drinking so I can go to bed, she stops drinking too (and she’s usually not super hammered by then).

She said lately she’s noticed insomnia & her seeing things in the dark that aren’t there. I think this is when the flip switches & the insomnia mixed with alcohol literally turns her into a blabbering, banging, demon. I don’t wanna lose my party buddy, but I can’t deal with her waking me up all the time anymore. I feel bad because neither of us know what’s been causing this to happen as it literally just started this week (2 occasions now). The only conclusion I can come to is it’s something to do with the allergy meds she’s been taking lately, but l’m not sure & would love to hear what you guys think.
