Yes, I am waiting for the doctor to call me back, but I am wondering if the CellCept I have been taking since October (500 mg 2/day) could be causing insomnia, and what can help me with it. I have only had ths for two days and do not like the idea of taking other pills. I am also on Mestinon 60 m 4/day, all for Myasthenia Gravis.Both meds have helped me a lot, so I really don t want to stop taking them if I can help it. I am 66 and also have Type 1 diabetes (on insulin).
