Why can't I feel it?

[brink]

I started smoking pot a few months ago and seized the opportunity to try ecstasy for the first time on New Year's. I took one red pill and I never felt like it kicked in. I assumed that it was just first-time jitters and that I maybe didn't notice exactly what the drug was doing and that's why I didn't feel it. So this past weekend I tried to roll again, this time with two Molly-filled capsules. They were each filled with powder that measured about 1/6 of the capsule and I swallowed the powder and then the capsules. Once again, I didn't feel any different. Is there something wrong with me? All my friends rave about ecstasy (haha) and I can't seem to understand what the big deal is. Help?
