Hi MarileeG, I will post my sleep study if it comes back with anything. I went to a nurse midwife who specializes in women's health for balancing out hormones, etc. I have gone to a naturopath who did similiar things though. A regular Dr can order the blood tests you need too. Mark has stated here a few times about what things to check. TSH (thyroid levels), Vit B, Vit D, Progesterone levels, etc. The TSH old standard range was .3-5.0, they have since changed it to .3-3.5 (you should be at or below 3 though). The higher level, the lower functioning your thyroid is.
