Re: Over medicated??
I think for a starting dose, it could be a tad high.
I'd talk with the doctor about moving ahead a little more slowly, decreasing the dose for now and working up to a higher one over the next few weeks.
The effects you're feeling are likely temporary and will dissipate as your body gets used to the higher hormone levels.
