How long does it take for estradiol to go up after stopping anastrozole?

Your estrogen will increase long before you realizes it, there is a lag time until your body will start to feel it which makes dosing anastrozole even more difficult.

I was unfortunate enough to experience the horrible E2 rebound affect, it felt like a front row seat to what a heart attack must feel like which forced me to give up on AI's entirely. The only way out for me was either taking more anastrozole trapped in an endless vicious cycle or stop TRT for a time to where there is less aromatization.

Basically I’m suggesting that E2 would come back earlier than 5 half lives. What say you ?
...
Depends how you define "come back". The "5 half-lives" figure just means that in theory most of the drug has been cleared by then. Because anastrozole works by competitive inhibition, as soon as concentrations start dropping more aromatase is freed up to start forming estradiol. So estradiol will start going up fairly quickly. But getting back to baseline could actually take the 5+ half-lives unless there's a surplus of aromatase. There's speculation that more aromatase is made in reaction to the inhibition, but there's no solid evidence for it as far as I know.
 
What were your symptoms?
My heart had never raced that quickly even while coming off benzos after 30 years, no comparison.
And these symptoms were due to the elevated rebound E2?
Yes they were, it's why I chucked the AI for good. I actually tapped out and took the AI again, then stopped TRT for a week so the E2 rebound couldn't occur again in a week.

I actually believe my left ventricular dysfunction diagnosis is the result of the 10 month benzo withdrawal.

Sounds horrible indeed

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
