My experiences have suggested to me, if you smash it one night and then try to it again during next six to seven days, it's no-where near as good.
However, if you give it two weeks before you next dose, you'll be able to achieve really good effects again. It's odd. I thought I'd fucked my fun with Mx for good a fortnight ago when I attempted to hole 4 nights in a row. The first night was awesome, massivfe euphoria and empathy and just a fantastic experience. The next night was good but underwhelming and nights three and four were shit. On the fourth night I did about 100mg+ and it didn't really do anything at all - seriously! It worried me because everyone told me tolerance takes months to go down. But I gave it 16 days and had some on Thursday and I achieved similar effects as I the first night of that four day binge. I tried to do it again last night and it was a good experience, but not as good as Thursday. See the pattern forming? So now I plan to give it a good two weeks between my Mx use
