I had a somewhat different experience. I thought that I had stopped breathing and that my heart had ceased (in actual fact my body was numb - I couldn't feel a pulse) so I stood in front of a mirror completely naked for the next 20 minutes staring at my chest. Thankfully reason stepped in and I managed to compute that if my pulse or breathing had ceased, I'd be in a heap on the floor rather than obsessing in front of a mirror. Suddenly I felt calm and proceeded to throw out some cool graphics in Photoshop and made an excellent puff pastry quiche. Again, without clothes.

My lesson was that drugs should be experimented with in the company of a friend or partner.
