Hey Tyson,

Sorry you're still having a lot of problems with the persistant sinus infection....

I googled that antibiotic and Myasthenia Gravis and it seems to be pretty contraindicated...It seems to result in severe weakness...It's the first med. on the list for medications to avoid if you have MG...

I'm not sure why this was prescribed to you (well, I know why), but it seems to be very dangerous....Are you able to get in touch with your doctor if you're feeling very weak today after starting this med., and since people with MG are not supposed to take this med.?

Please take care....

P.S. Jana's idea about vaporizers is a really good one...
