peppermint patty and jenny, My story is very similar, I have NCS and OH. As far as false positives on the TTT I'm not buying that because a person can have convulsions its not ,necessarily, just "a simple faint". Also I've had 4TTTs. They recheck after trying new meds. Passed out during all 4. I don't think 4 false positives are likely. And jenny I had to laugh, I would say I collapsed but was not out too. That was my experience. Onlookers might tell you different. Like the Dr. doing the TTT. I also seize when I faint- who knew!
