I tried LSD for the first time a few weeks ago...it tasted quite bitter. I've been told if its bitter its probably more likely DOB..but I thought DOB took hours to take effect. I started feeling something off this extrememy quickly (probably about 15mins) ..but wasnt peaking until about 2hrs later. It lasted a very long time..I'd say about 18hrs and not feeling all there for a few days. I didnt get any visuals..but things definately looked 'different' and it felt intense..well I maybe did get mild visuals as things looked out of focus/off balance. I felt really stoned but full of energy if that makes sence .It was quite strange though as for the first 3-4hours I had massive uncontrollable giggles and simple things seemed extrememly challenging..was really enjoying it..but after that I started getting cramp and felt like I had energy surging in my upper body..but this energy feeling made me really restless and uncomfortable and I spent the remainder of the trip feeling agitated and a bit bored! I felt almost like I was either on the brink of coming up constantly..or the brink of coming down. I never really felt anxious throughout apart from once but managed to ignore it..I just felt really frustrated! Any ideas? I was thinking too low a dose..not lsd..or lsd just dosent agree with me physically?
