Nicky, The "fancy" name for Mestinon is Pyridostigmine Bromide. They are one in the same.

Since the Timespan works for you, I'm wondering about the status of your GI tract. Are you on antacids? Not just Tums but the nasty ones like Prilosec? That will get rid of your stomach acid and you will not digest those little tablets well enough. But, as the Timespan goes through your body, there may be enough of it released later to absorb. Get it?

Maybe if you try the Mestinon syrup, which I use due to no stomach acid, it may absorb better. Worth a shot.
