I use to be all up on the altered state of consciousness boat and was well on my way to trying acid but was shipwrecked by a bad trip on shrooms in my 1st year at university. Used to love em, the conversations, the epiphanies, the closeness to nature, and the general hilarity of it all. Then, Halloween, thought a good day trip followed by a night of partying would be a good way to honor the Great Pumpkin. Long story short, took wayyyy too much (accidentally took nine grams instead of 4.5, I was high, I should've known better) and had the worst experience of my life for next 6-8 hours. Ever since, even with super small doses of shrooms I get the same feelings, which I would generally associate with guilt and overwhelming despair.
Sparknotes: took too many shrooms, had a bad trip, now i almost always have bad shroom trips due to feelings of guilt and despair.
Now, my question is this, will I inevitably experience similar negative feelings if I try, say, a 1/4 or 1/2 hit of LSD? Or, is the altered state different enough that I won't associate it with the craptastic effects that shrooms have on me?
