I give blood every eight weeks (i've done this for years prior to NBE) and stop all NBE for about four days before I do so and pound water like crazy to flush (I've done it twice so far).

Afterwards I start again and ramp back up. So far I have had two eight week cycles and let me tell you... I feel great after a few days back on and I got a pop of growth this time, too!

If you are looking for a way to make the cycling of your NBE a bit more realistic, this may be a way for you to do it.

Interesting idea Emily. I'm also a regular blood donor. (I made a donation this week in fact). Not too keen on going cold turkey with pm though. Right now I'm relying on progesterone cream to help advance my progress.
