AI's can really mess with hormone balance as well. The first time I took erase I made the mistake of starting at 3 a day (was also taking 3g DAA per day). My body did not like that at all.
Erase should be respected. It will mess with your hormones, because that's what it's intended to do. I've learned (the hard way) that for me, the best way to take erase is to taper up. Also, I don't take AI's unless I'm taking test.
. . . that's what works for me.
