Anybody who tries to put a timeline to recovery is speaking without basis. Often, you have just not found the right angle of attack. There is always hope for ways to improve.

What A/D's are you taking ? Are you taking more than one ?

I really encourage you to look at the vitamin and supplement regimen. Plus, get some blood work done. Hormones, B-12, Folate, Mag, etc. If you can find a specialist in 'life extension' and 'maximizing potential' you may find some weakness in your metabolic systems and such.

My best to you.
