I've never been out of control on acid or shrooms.
In fact, I feel strangely in control, which is contrary to what other people say.
Often I have strange experiences that happen to me. Example, I was riding my bike while coming down from a trip and some assholes drove up beside me in a minivan and threw a bottle at me. It broke on my bike frame, but I was completely unharmed and completely unfrightened or even angered. In my normal state I would have probably freaked out and tried to kill them if I could catch their minivan.
Another time on acid I broke up what was about to be a nasty fight between some jock douchbag and a hippie with a broken bottle. Again, the bike... I just rode my bike right between the two and told them to walk away. This was at a college music festival.
I have gone on long swims in the ocean while on shrooms. Deep water. And I sometimes get cramps while swimming, but still, it was a great experience.
I also came up with the idea for my horrible book while tripping.
Sadly, however, I feel that acid (not shrooms so much) diminishes my logical abilities, which I rely on for the work I do... so I cannot trip often. In fact it's probably been about 20 years since I have.
Maybe it's time again.
But then... I'm in a country that has very harsh drug laws, so I probably won't do acid until I get back to the states (if ever). Shrooms however are readily available, and no one seems to much care if you trip on shrooms here, but selling them would be a big no no.
