Me and a friend dropped 1 hit of LSD at 6:50 pm. We started to trip around 8, but it was incrediby mild. We decided to half another hit, smoke some, and then go to a friend's house. I tripped great with her until about 10 pm. Then a bad trip started to take over. I was panicing out our friends so bad that we left. I had this feeling that something horrible would happen, and i couldnt overcome it. At 1 my boyfriend finally came to pick me up because i needed someone. I kept him awake the entire night. At 6:50 the next morning i realized i had been tripping for twelve hours, and i didnt feel like it would stop. I never did fall asleep. Around 8 am I decided i felt okay. About an hour later i started crying hysterically just because i felt scared. I did this probably ten to 15 times the day after dropping. I smoked with some friends about 3 pm the next day, and it started to make me trip again. I felt like they felt were so loud, and animated to. After getting high i felt like i tripped until I finally fell asleep  at 11 pm. Why did my trip last so long? Did it continue because i couldnt sleep for 36 hours?
