Hi, Welcome to Health care magic forum.
I understand that you are at the maximum dosage, otherwise you should be comfortable, Or the weakness may be due to the
breast cancer it self, as it was at 3rd stage.
As you think, it is important to get out of
cymbalta. Instead of trying by your own self, it is advisible to
consult a psychiatrist for deaddicting the cymbalta.
After treatment of the breast cancer one will be very week, and nervous, so You should take care of your health, first.
Take more of green leafy vegetables, pulses, sprouts, and proteine rich foods.
Especially i find in convalacense of breast cancer, the fresh juice of palatable vegetables daily giving a very good result.
Wishing for a quick and complete recovery. Thank you.
