m in the process of reducing my daily dose of pred from 40mg to 5mg. I am now down to 9.5mg and the brain fog and depression have now gone - thank goodness. However the chronic fatigue hasn't and I am becoming very fed up with having to have a sleep every day and being unable to walk for more than thirty minutes without being puffed out. Also I have now been told I have type 2 diabetes and have been prescribed Metformin twice a day. I know that fatigue is also a symptom of diabetes but its difficult to exercise when sometimes you havn't even got the energy to make the bed and your GP says exercise is good. Has anyone else had the same problem or am I being hasty in wanting it gone. It is almost two years since I was diagnosed with GCA and I am hoping that this time the reduction will not result in a flare up. I also take Mycrophenolate but I do not think that this drug causes fatigue.
