Well, there is a lot to consider with LSD. The first being that it frequently isn't lsd. There appears to be a lot of 25x-nbomes getting sold as lsd. If you have one, you will taste it. They taste bitter, and if you swallow one right away it will have absolutely no effect. You want to make sure what you are taking really is LSD.
There are countless blotters, liquid etc. Some of it can be pretty fucking nasty no fun shit. You don't want that. I believe the odds of getting the good stuff in liquid form is better, but so are the odds of getting watered down crap.
The experience from 1 hit of LSD, say 80ug is far different from the experience at 350ug. Night and fucking day. The typical theraputic dose back in the day when it was being given out by researchers legally was around 250ug. This brings up the whole how much should I eat question. Jumping right into 250ug can be, shall we say unpredictable. Eating a single hit and thinking you've done LSD isn't really productive either. My recommendation is to take a small amount first just so you can see how well you tolerate it, then after the tolerance period, eating a bunch. Don't be one of those pussies who never makes it past a hit. Expect to not sleep for up to 18 hours, 12 at a minimum so plan accordingly.
IMO, LSD sucks, makes you all jittery, fucks with your head and makes you think crazy thoughts. You can drink alcohol to try and deal with the jitters but it does't fucking work. The only thing that seems to work are phenethylamines. Have some 2C-B, MDMA or similar substances around. You will thank me. When you start thinking, oh god this is so fucked up, why the fuck did I do this... take the MDMA, 2C-B etc. You're gonna think, really, I'm feeling all freeky, shakey and the walls are breathing and you're telling me to take even more drugs which also happen to be stimulants? Yeah. Do It. You will feel 10 times better after you do.
