Good call.
I would get some letro and start gyno-reversal immediately. taper it up to 2.5mg/ed and back down. Be warned though, you're going to feel like absolute crap. Having 98% of estrogen eliminated from your body doesn't make you like "more manly"

or anything -- its the exact opposite.
You might have been too late last time... but if you being eliminating all your bodies estrogen right now you may have chances of completely reversing this current case of gyno.
Glad to hear you're going to stick w/ a-dex in the future. If you notice gyno reoccuring in the future then bump to 0.5mg/ed of a-dex (but that's quite a bit. .25mg/ed should suffice.)
Best of luck
