I didn't feel it, but you can't gain a couple of lbs of fat a day, so it had to be water. In a few weeks it all went away, I assume my TOT T and E2 both drifted back down. The weight all went away in 2 days.
It's possible if I had tried to maintain a E2 of 56 maybe my body would adapt and I would lose the weight anyway. But having TT that high didn't seem to provide any obvious benefits, so I let it drift back down.
I suppose I could have used an AI, but why bother and it's so easy to overshoot with an AI, it will naturally resolve on it's own without my introducing another unknown. And I have never used an AI so I don't know how I would react to it.
The one thing that was interesting, it seems with much higher TT my conversion to E2 was 4% instead of the more typical for me of 3%. I didn't test SHBG so I don't know if that changed.
