Does anyone have Myasthenia Gravis (MG) and take TF, and is the respiratory one the one to take and what is it called and is it supposed to help with immunity against resp. bacterial and/or viral infections. are there any that boost the metabolism/fatigue as I have put on 35 pounds in the last 9 months and was diag and started mestinon am still so tired. My fibro is much worse so my activity level is at a screetching halt and depression is worse too. Any TF for these problems?
