Hello wonderful ladies, I started HRT 2 weeks ago at age 45 after suffering the most debilitating anxiety and panic, in addition to increasing night sweats, long/heavy periods and all the other joys of perimenopause. Since starting Estradot 50mcg, I've overall improved but I find that I have some pleasant highs as well as really awful lows. My mood crashes and symptoms return with a vengeance if I leave the patch for longer than 3 days - even 3 and a half days is too long - and then sometimes when I do put a new patch on, I feel really buzzy, restless and nauseous for about 12 hours. Teeth grinding and agitated, the lot. I can only describe it as feeling like I'm on drugs (which obviously I am). I'm a bit anxious as I haven't even started the utrogestan yet (that'll be tomorrow). Should I just persist at this dosage, and will the rollercoaster eventually level out? Or do you reckon I should go up to 75mcg? I'm with the Newson clinic and have another appt in 3 months so am just trying to tweak things myself in the meantime. Thanks in advance.
