I been thru hell the last 2 weeks, vision blur lightheaded hot flashes sleepy lethargic foggy brain the list goes on.. so finally convinced the doc to a blood test on androgens and Oest2 level. Turns out the damn estrogen level is high off the roof again.. so here is the results Oest2 measured pmol/L is at 300!! normal range for a male should be <150.. now here is the thing I think my arimidex no longer works for some reason so I switched to aromasin. I need some help on the dose. I got tabs that r 20 mgs which I cut them in half. so 10mgs ed so far this has been my 3rd day. feeling bit better but still suffering from lightheaded and vision blurs disturbed sleep. should I keep doing 10mg a day or eod, eo2d? I want to keep my e2 under control but not too low, and how long does it actually kicks in?
