Talk to your Dr. you may be taking to much medication. My MG also came about during my pregnancy and after my thymectomy I was feeling better and then crashed.. I weaned off my meds and went into a drug free remission for 17 years. I was not able to return to work at the time so my maternity leave turned into long term disability. Once in full remission I took it easy for fear of it returning, now that it is back I do not work nor do I take meds, I try to control it with rest. Everyone is different so as I said, speak with your Dr. I wish you luck and hope you go into remission soon
