Hi, Ped, Went back over the previous posts you wrote and I think Jo is right, you probably aren't getting enough rest but to be safe go get blood work done. I am almost four months post op now and still have tired days. I don't know how old you are, I am going to be 67 soon and I think that has something to do with it. I know the days I am tired usually follow a day when I did too much or a night when I didn't sleep well. I take a multi-vitamin and while I think everyone should take a supplement I don't see mine doing anything spectacular, like pepping me up. Good luck. Rowdy
