I suffer from Diabetes II, and currently take Invokana and Junumet. Up until May, I was exercising daily, and feeling good. However, since March, I have loss 20 lbs, and have no energy. I have had a chest X-ray which was fine, blood work which was not abnormal, and a CT scan which reportedly was returned normal. I am 54 years old, but am struggling to feel better, and have more energy. Any suggestions?
