Gidday doglover, I think bouts of depression and memory loss is reasonably normal for us who suffer mg, I am on 25mg prednisone and 60mg mestinon 4 times a day and sometimes it is really frustrating trying to remember something simple and everyday being on prednisone has tripped me into diabetes and I take high blood pessure tabs too, I get bouts of " fuzziness " and really feel depressed too especially on those gloomy overcast grey days, but bright good days do come too so I try to enjoy those to the fullest, go for walks in nice places along the river, you have to keep on going and try to be upbeat taking of dogs, I like " jack russel " terriers, I dont have on but if I got a dog that would be it, did you know they suffer MG too, regards john
