I had been on 50 mcg for about 6 weeks when I got diagnosed. After the first 2 weeks I felt so much better- more energy, more getup and go and hardly any feeling of depression. I went up to 75mcg as of Monday this week and for the past 3 days I have felt exhausted and depressed. As this is my first dose increase I am unsure if it is because of this/other life factors or a combination. Is it common to feel awful when your dose increases and almost back to square one and if this is the case, why does this happen?
