Had alot

Had alot last night after not drinking for a long time and I weigh only 130lbs, had my last drink at 130/2am and went to bed and only got 4 hours of sleep before having to get up. I had a very bad hangover and noticed at around 6pm I feel tipsy almost, not traditional but things feel wonky almost like ive drank but i know i havnt. Could it just be the lack of sleep but I just want to make sure it’d not alcohol poisoning or something like that.

Thanks in advance!
