Now taking 60mg Mestinon three times a day after a week of 30mg. Some odd immune stuff. A small cold sore (even though I'm on 2g Valtrex). Face is breaking out... been a long time since that happened. Feeling flu-like/PEM-like immune symptoms, but I'm not in PEM (at least I don't think I am). It just seems my immune system is a bit confused on Mestinon right now.
