I tried LSD recently and absolutely loved it, about how long is your ideal "healthy" break from LSD? It's been about 6 weeks for me. I would love to do it again as soon as possible, however, i understand what a potent substance it is and wouldnt like to abuse it.
i'd say at least a month in between (although i'm also quick to make exceptions: if you're planning a totally bitchin weekend, its not gonna hurt to trip two nights in a row or three times in a week. the issue isn't really physical damage, just avoiding getting too mentally spun out. so make exceptions as you please, but keep them exceptions, not habits)
a week is fine for me sometimes, and othere times its several months. there is no real time limit and it changes for me all the time. but i usually trip 1-2 times a month
