Is it the same acid as you took a week ago? Maybe you're doing it too often
This.
Unless you're fifteen years old or a member of the Grateful Dead touring party, you need to take a couple of weeks' break inbetween doses of acid, at the very least.
You're just pissing away perfectly good drugs and unnecessarily screwing with your brain chemistry otherwise. Take it from somebody who got bored of such antics years ago: LSD tolerance shoots through the roof very, very quickly.
