LOL well on acid your head won't ache it will throb so be prepared for it anyways LOL at least with my experience it doesWell.
I've been drinking water all day and I had a headache earlier but tylenol took care of that. I guess since I've been flushing out my system all day I'm getting better. My throat isnt really hurting anymore. So hopfully tomorrow I'll feel close to 100% well.
Just as a precaution I'll take a tylenol before I trip so I can prevent a headache from starting while I'm tripping
