Best trip I ever had was with ecstasy and mushrooms. They mix fantastically. I ate half an 8th of mushrooms first, waited either an hour or half an hour and then took one tablet.
I remember being in the woods when I noticed the ground begin to swirl. Then I went to piss and the ecstasy hit me, everything was great. Next thing I knew the trees were looking at me, with so many faces. After a short car ride I had felt like I had a mental breakthrough.
