i`ve tripped literaly hundreds of times over a 10 year period most i`m glad to say were good trips but inevitably there were a few shockin nights . i`ve taken both shrooms and acid in large doses, shrooms being the most....adventurous shall we say(i was able to sit in my parents company while on acid, provided I came up in their company that is) but mushrooms ...no chance. They`ll pick you up an throw you around make you want to stand up , sit down , lie down, jacket off ,jacket on, roll a spliff , fill a pipe instead an generally talk the biggest load of shite that you`ve ever heard , and you MUST talk this shite , if you think it and don`t say it then it doesn`t leave your head, nope it fuckin stays there an amplifies itself an clouds all the other mental things you have to get off your chest until there`s a backlog of shite in your head that is all being held up by that first lot of shite that you thought of, and in the meantime , your not talkin at all , then you realise you`ve not said a word for what seems like ages and all the backlog of shite disappears leaving you with only one train of thought, " i haven`t spoke for ages...fuck, naw, aw whit, am cold" hahahaha. Sorry back to the point . Don`t go with the( don`t think bad thoughts theory) the fact that your already thinkin them is a pretty good indication that you`ll be thinkin them on the night. I went into all my trips with an open heart an mind an generally didn`t give a shit. If you aren`t in this frame of mind then try alchohol, I found this to be a good way of "not givin a shit" it dulls down the intensity of your trip but without dullin down the hallucinations. But if you want the full effect an are still wary then I suggest you get yourself some valium or temazepam or similar an drop them if the trip becomes to heavy for you. Good luck they`re really fuckin mental an I loved them but really need to be takin when you ain`t got shit to give a shit about . Have fun
