^ same with me.
There were events, always psytrance party (anyway the only event where i imagine to be able to have a pleasant trip at all) where i took high doses LSD and had a "good" time. There were always some other drugs involved, at least some beer. And there were a lot of situations and times were it got to strange and i weren't able to handle the situation appropriate. After doing this for about 2 years nearly every weekend i got quite fucked up and had to stop all drug consum for about one year to clear my head. It took some time to regain a perception of reality that represents my life in this environment (society, family, work, etc..) in a way that made my behaviour compatible to the environment. But you see this was an individual longtime behaviour of unawareness and missing respect towards LSD and drugs in general.
In general it is possible to have a good time at a rave on acid - try to make sure you will enjoy the music, the people with you and the location etc. as far as you can. In any case tripping in public situations always encounter the problems that can happen anytime. I.e I got robbed, had a car accident (wasn't the driver ) and saw how someone sliped on a stair an fell on his head badly (open wound, unconcious, fortunatly there were more people that were able to help better than me). All this events weren't that enjoyable while tripping, though i doubt they were any better if i had not been on acid. All in all you should be prepared for anything
Nowadays i mainly enjoy pure and clean acid trips much more. Love the clean open feeling so much that i almost feel it is a waste if i for example drink or smoke before or while i trip. In the end it is always worth tripping as long as you respect acid - otherwise it will kick your ass, sooner or later...
I couldn't drink on acid... the taste and the texture is too weird, not to mention you are usually dehydrated anyways.
I've had a number of bad things happen to me while being on acid as well: friend locked his keys in his car, best friend went crazy (trying to find things that didn't exist in my house that were his and not wanting to leaving until he found them... parents house, 12 police officers had to tazer him out of my house), bad break ups. But for some reason acid is one of those drugs for me that no matter what could possibly go wrong, I am still very positive about it all. My writing skills are not great, but my talking skills are pretty good.
my girlfriend cannot use MDMA due to her using an SSRI, so last year I introduced her to LSD at Electric Zoo. she had the time of her life.
For festivals, acid is a no-brainer. it's perfect. the only real issue is in really compact settings it becomes easy to get skeeved-out by all the nasty sweaty people rubbing up against you, but i've found that a little j of some good bud not only calms you down, but also throws an interesting element in the acid trip (kicks visual distortion and body high into overdrive).
have done Lsd in raves a few time. can be a brilliant experience but can also be overwhelming, confusing and scary. just make sure you have someone with you who knows what you doin incase shit goes down hill.
