Totally non-snarky answer here: For the last ten years, I've been getting headaches if I drink alcohol, any kind, but esp big/fast headaches with wine. My nose gets all stuffy, and my sinuses & eustachian tubes (ears) ache. Every time. My body is telling me, in pretty clear ways, that alcohol is NOT GOOD FOR ME.
That being said, your reaction to weed, even just a coupla hits, is very extreme, and your body is telling you, in pretty clear ways, that weed is NOT GOOD FOR YOU.
This might not be forever, but just a right now sorta thing -- I'd lay off it for more than a week, as passing out after 2 hits....well, you're gonna have a bad time, ummmkay?
Best of luck.
