I will agree that mushrooms in high doses can really blow your mind. But for me, mushrooms are less anxiety producing than LSD. Even when losing touch with everythin on shrooms, I am able to relax and just go there, whereas with LSD I was finding that to be more and more difficult. Also, after doing several trips on over 1000 mics, now I can take just 500-600 mics and trip hard as holy hell. With shroomage I still just ake one dose, a big one usually, and go with it. Even taking a half ounce at once does not cause panic, although there is always a little bit of fear for me.
LSD is the drug that makes me wonder if I will ever return to reality. The last few trips I had scared me badly even though they were not total freak-outs. Most of you familiar with LSD know the difference between a bad trip and a freak out.
I have freaked on shrooms, but only once, and only on about 5 grams. I still don't know what happened. I just freaked right the fuck out. My friends watched me scream and holler, but did not take me to the hospital because they were able to see that I was just freaking out and was in no physical danger. To this day I thank them for not panicking.
Anyway, I do not find shrooms and LSD to be even remotely similar. Maybe if someone just took threshold doses they would be similar, but that is only because the experience itself is not comprehensive on small doses.
I determined for myself that somewhere around 700-800 mics LSD things are the most intense. Increasing the dose, even to 1500 mics, only seems to lengthen the trip.
Same with mushrooms. I have eaten an entire half ounce of dried cubes many many times, and even though the trips are usually VERY intense, they still only last about 6-7 hours. 1500 mics LSD had me tripping for over 30 hours. I thought I was going to trip forever.
I haven't done LSD since 2000 because I am genuinely frightened to, and cannot say why.
