I did stop taking RU because I was getting terrible brain fog and fatigue. I might try a lower dose because my hair is getting terribly thin. I don't think I used it long enough to know if it slowed down the shedding, but it definitely started growing hairs.
The minoxidil didn't help much. I probably used for 2 years and nothing promising so I stopped.
I did try both Propecia (1 year) and Avodart (over 1 year) and neither slowed down the shedding.
I took a few capsules of the iodide but I stopped because I have my endocrinologist appointment is coming up on Nov 3rd which I will have tests done. I don't want to screw with my system before I have the tests.
