Hey man, I had/have the same issue as you - beat the hell out of my estrogen recently. Like you, I also stopped it for 4 straight days, but now am back on at .25 E3D. The thing is, who knows if my dose is correct now - but its a start. You can't just chase your estrogen around with boners. It will be a never ending battle. Pick a dose, and stick with it for a while, like more than the next expected morning wood.
Anyway - just my thought on it. Even if you can't get blood drawn often, you can atleast pick a sensible dose and let your body has it out for a few weeks. At the rate you are changing things, you will never get a base.

Jim, thanks. You are right, I don't think the boner test is the most reliable way to gauge E2. I think .25 mg E3D is the dose I am going to stick with for a while. I figured I would give myself a good week without adex before starting again. I really don't have any symptoms of high or low E2. Just wish I had higher libido, but hey, maybe I just have to accept this is the way it is at 59. I was on androgel, but recently switched to injections, 2 weeks now. But I was told that it could take 6 weeks for it to build up in my body, so I am also doing one pump of androgel 1.62 ED to keep my levels up.
