Anon, there was a break about six months, broke, the trip lasted about a day. Everything was going well, heart rate and blood pressure were under control, everything was standard, considering that I was under meth. The strangest thing was after the end of the session, about 2 hours after the last trip, I start to feel a very strong heartbeat in my ears. Measured, pulse - 170 (in the trip did not rise above 130). Sinus rhythm, pain was not, a little lack of oxygen, and a very strong anxiety simply because of the fact of such a pulse. Is it worth worrying about this, maybe someone has? Moreover, the pulse was not knocked by beta-blockers and phenobarbital. It became weaker (worse felt), but the frequency did not decrease for quite a long time until it knocked out.
