I had a pretty crazy trip on hbwr seeds. They took ages to hit, like five hours. I was convinced they were weak or totally bunk and upped the dose at a few points and ended up taking 17.

Started having truly wild stomach cramps, felt like I was being stabbed. Lifted up my shirt and looked in the mirrior and my abs were contracting comically visibly from left to right. "THAT CAN'T BE GOOD" i thought as I automatically assumed toilet-hugging position, my home for the next two hours as I tried to force myself to throw up and the "call your parents and 911, you've poisoned yourself" devil/the "you've read everything there is to read on the internet about these, it'll be fine later" angel on my shoulders waged war.

"OoOo you might feel sick before the trip starts, some people throw up. It can cause muscle cramping". <-- very funny jokes told by a demon. Two hours of excruciating pain later i finally threw up, rocketed to the verge of breakthrough psychedelic territory and had a super fun time for the next 12ish hours. Fell asleep for a couple hours and woke up still mildly tripping through a dentist appointment and half of my shift.

10/10 would not do it again.
