Acid s all right I've tripped maybe 30 times LSD and too many to count shrooms. Amongst an array of other things and I'm still here to tell the story. I think overall psychedelics have made me smarter not dumber.
The prob. With acid over shrooms is that it's man made and many times made by sketchy fucks that don't know what they are doing so you never know what your gonna get. Start small .do a half a tab then build from there if you like it. Like I said though. I really depends on how good it is the potency etc.. So you may have to shop around till you get what your looking for.
My college room ate was a dealer at phish shows and dosed a whole sheet (100 tabs) he was hospitalized for an entire year. And was still having problems 4 years later when I met him.

I still take shrooms on occasion but the older I get the harder they are to find. I'm currently looking to try ayahuasca.

One more story. My exgirlfreind traveled to the bush in Africa for a month and lived with a tribe of pygmies (I think) to apt entice as a ibogaine shaman. She was always pretty cool though.

Good luck bro!
And Remeber .the only thing you have to fear is fear itself. That is very relevant when tripping.
