Sounds like you did crash your Estro.
Where's the Arimidex from, is it Liquid or UGL or Pharma-Grade.
Sometimes Liquid or UGL can be Overdosed, that's why I only get Pharma-Grade.
You have 1 Mg. Tabs, is that correct.
So if you split them in half, it would be 0.5 Mg.
So if that's correct, and it's Too much, go to Every Third Day, instead of Every Other Day........................... JP
P.S.
Everyone is different when it comes to AI's.
So just keep a Journal of what you're taking, how often, and how you're feeling.
This way, you can Zero in on the right dose for you.
