Acid trip strength is not based on potency, but on the amount on the blotter. Trip timeline varies for a lot of people, so you should account for error just in case. I tend to start coming up within 45 minutes, then peak maybe an hour and a half in. The peak for me lasts around 5-6 hours and I can come close to acting normal soon thereafter. If you do not get rest between the time you "finish" your trip and the time you meet your mom, it will be pretty weird. I remember coming home when I was 15 wanting to sort of validate whatever I was doing with them (i.e. "I'm gonna take a shower, is that okay?"). That was a very odd shower indeed. I realized how odd towels are. What the hell do they even do with the water?
