You did not do acid. In fact, the chances that you've done real LSD before is near 0%. What you did was a research chemical. Most likely an NBOMe of either the 25I or 25C variety. You will be FINE this time. So don't flip out. Seriously, things almost never go wrong with the compounds if a competent chemist made them. Enjoy the rest of your trip. Go enjoy nature. Fuck staying on the computer. HOWEVER, do NOT do them anymore. They've only been around for a couple years in mass production and a bunch of fucking people have died from them.
