Thanks Annie.

Sorry Celeste I am not on here enough to have got to know everyones personalities! I know that I can come across as quite direct so I apologise if any offence was caused!

Dar - there are so many causes behind a faint it would be wrong to blame it on a medication before having a full evaluation such as a Tilt Table Test or blood tests to check you dont have something like aneamia (spl?). There are also many medical conditions that can cause you to faint. I have Ehlers Danlos Syndrome. Which causes the blood to pool in my legs on standing or even sitting with my feet touching the floor. I have to sit with my legs at the same level as my hips or I will faint sitting down - hows that for a talent lol! Thats why no medication - even mestinon is ever going to cure my fainting as it cant change the Ehlers Danlos syndrome!

Even eating a carb heavy meal can provoke a faint in some people.

I hope you get to the bottom of your faints but I do feel that mestinon probably isnt the culprit and something else is going on such as problems with you autonomic nervous system due to MG.
