Side effects - Mushrooms and Racing Heartbeat

[kinka]

Well,I used to really enjoy weed, but I've stopped smoking it since 5
weeks now, because I had an experience where, just before seeing nice
things, I felt a 'pins and needles' kind of feeling in my heart, and
then felt it pumping liek hell and I could see it pumping through my
shirt, although everything I concentrated on was wiggling a lot.

Anyway, my heart hasn't really felt too good since then, but I love seeing things so much that I need something new.

I've never done shrooms before, and have heard that there's some which
don't affect the heart. Can you give me as much advice as possible on
this subject, please?

Thanks a lot, guys.
