Def try to keep your adventures spaced out (uh, as in time). As some who's taken large quantities of acid and shrooms (usually in tea form) I can confirm that you lose quite a bit by doing them too soon. Remember that every time you trip a part you you changes.

I haven't tripped in about 20yrs but I still get crazy flashbacks, mostly visual. At the bar around Halloween this year my wife was talking to me and using her hands a lot. I started seeing mad trails off her hands and eventually had to grab them and stop her. Within minutes a friend walked in wearing a raver costume with glowsticks and shit all over him. My wife just looked at me and started laughing. I laughed my ass off for a minute and walked outside for a smoke. Of course the raver followed me out. He stands right in front of me and starts twirling these fucking glowsticks on 2 ft long strings. It was seriously funny but I finally had to make him stop. Meanwhile my wife is watching all this and laughing her ass off because she knows what's happening. This was the longest flashback I've ever had, maybe a half hour or so.

I think it was led zeppelins the song remains the same, which I've watch many times while tripping. If you haven't seen it I suggest you do but wait until you do shooms again to watch it for the first time.

On a side note, the only psychedelic I've done recently was DMT. I'd suggest it to anyone who digs shrooms. There's a thread about it somewhere here.

Have fun.
