If I go on 125 will I need to increase again in the future??
Funny thing the last few days I feel foggy head, cold (have my heating on) and want to sleep all afternoon. Do you use HRT??
Maybe and maybe not. I was warned years ago that when I hit the menopause my levels could fluctuate and they did but since I am post meno they are more stable again.
Those symptoms show that you need more thyroxine and you should increase as you have been advised by your doctor. Don't be scared of it, thyroxine is not a drug, just an essential hormone replacement
I only use topical Vagifem for vaginal atrophy, I never used full HRT because I wanted to avoid too much instability in my thyroid hormones and I never felt I needed it.
