Hi, a few questions for you. WHat is your age? have you had your estrogen levels tested? (saliva test not bld) Also, MOST ppl are deficient in Magnesium. which helps to process stress and allow the body to relax. you can rub Magnesium oil on your feet at night (pores in feet are larger and allow better absorbtion) AND take Chelated Magnesium Glycinate. You can start with a 300mg pill and go all the way up to 750mg. I currently take 600mg as Rx from my Dr. it is available through vitacost. You can also take a hot bath with Epsom salt and lavender before bed. Lastly, get at least 30 min of sunlight exposure upon waking, this sets your cortisol production to help reset your sleeping pattern. Hope you get some zzzzzs soon!
Good possibility that you need to increase your med, but really need to have a look at your thyroid test results, along with reference ranges, in order to better assess.
