Is Depression and tiredness related?

Please don't stop taking your your medicine. It is too soon and when you do it you have to do it with doctor approval and wean yourself off by lowering dose before going off completely. Talk to your doctor. Maybe it is a side-effect maybe it is a symptom of the disease and he can add or change you med to one that gives more energy. Make sure you aren't sleeping too much, try to get some exercise and make sure you are eating right.
