I am still working after only 2 months of MG. I drive a company vehicle as part of my job and the 1st month until the right dosage of mestinol was driving one eyed. The most I drove in one day was 250 miles and I really felt that for a couple of days. But I feel like I will be able to continue working now. My muscles really ache in the evening but at least I have a paycheck coming in.
