I found that to be the case with Turpentine as well I used too much in a bottled water and it didn't peak until hours later at night and it had my nervous system going crazy I couldn't relax or sit still the fight or flight response was horrible I had to chew some Ativan just to calm myself down. You never know how you're going to react to something that's why you don't go over board with whatever it is you're taking. I think the Turpentine can stay in your system for 15-24 hrs. Idk how people do large doses of that stuff it's a very potent stimulant.
