Have you tripped recently? If so you could be building a tolerence. I have heard, and noticed that while on anti depressants of the SSRI family, my trip is never as intense. Also, did you eat before or during the trip. This could increase the time in which it takes to get from your stomach to your bloood. I'm in agreement that you gave us absolutely no information. I feel like you are asking us to perform psychic reading for you LOL> j/k
