drinking on seroquel

So I’m in college and decided to drink for the first time (like ACTUALLY drink to get drunk). I got home at like 3 am and took my 50 mg of seroquel (I just dropped from 75 to 50 mg and I’ve been on it since like July after a manic episode) I felt fine the next day and went out to drink again on Saturday and had a bit more. Then on Monday I was sick. But on Tuesday, Wednesday and Thursday, I felt dizzy all day and it didn’t go away until like late at night. Does anyone know if this is because I lowered my medication (I lowered medication like Jan 12th) or drinking interacting with the medication. I haven’t drank since Saturday but I still feel like the side effects from the first day?
