there is a risk of mental illness ONLY because you are concerned about it. if used in a good set and setting there is no reason to believe that you wouldnt be better off "at the end of it all."
not true! you can re-dose up to 12 hours later without tolerance. of course the initial shock is not there so your second and third dose may not seem as intense. if you take 2 then take 3 four hours later you can actually notice that you are much higher off the 3 then you were on 2. if you dose again after 12 hours you can notice a big tolerance. how people can be so sure of themselves when they have no experience is beyond my abilities to understand. - dont believe everything you read or hear. sometimes you have to experience things for yourself.
Yeah, I wouldn't be worried if I was you. Just let the trip do what it needs to do. Trying to rationalize on LSD (at least in my case) gets me crazy. Worrying over half a tab? I wouldn't be fucked to only take 1 of my cities shit. The blotter in my city is so weak and overpriced I think I'm sticking to RC's. 5 Hits for $8-9 bucks each and sometimes it won't have much over a threshold effect of lame tracers and shit
