I am on day 3 of the 1mg tablets (estradiol and estradiol/norethisterone acetate). Am early 50s, no period for 10 months. Finally went to the GP as my main symptom was anxiety and not wanting to drive (after driving for 30 years). Am feeling very tingly and light headed. I still don't want to drive but am pushing myself. How long should I try this type of HRT? Still feel anxious and some days feel I am pushing myself to go outside. Thanks.
