You can definately trip again this weekend. Just make sure you take a whole 1/8th at least. I did a lot of shrooms this summer, and one week i did them 3 times(best week ever) and the second time i noticed a little different trip, not better or worse, just different, i guess not as laughy of a high.

The third time was on the weekend, i went hiking and tripped during the day, it was fucking awesome.
