Lately the last few times I've smoked hookah, I've gotten a pretty healthy headache. I was wondering if this might be from the coals (Belgian Instant-Lite Charcoals, the freebies that came w/ my hookah) or possibly from the tobacco (Layalina). I smoke only occasionally, generally once or twice a weekend, and I definitely have not always felt a headache. I'm sorta clueless, should I maybe look into some natural coals that I hear about or maybe a different brand of tobacco tends to be better. Otherwise I feel I'll just keep taking a few tylenols or something before I smoke as I do enjoy my occasional hookah smoking session.
On another note, maybe it's my weak nicotine tolerance?
