I too am on medication "Synthroid" 0.25mg for Hypothyroidism. The night sweats should not be related to the underactive thyroid. I take Evening of Primrose Oil capsules (1000 mg.) 2 in the morning and 2 at night and they help with the night sweats I developed from Peri-Menopause. I recently had my thyroid levels checked too and everything was normal. I also take "Estroven" which is a natural Vitamin and Horomonal Supplement with Soy and other plants, plus vitamins B-6, E & Calcium in it. That worked wonders after only the 2nd night. No more night sweats! It should be around $10.00/box of 30 caplets in the U.S. You can get it at Walmart. Hope this helps, it sure helped me instantly!!!!
