''However, I do not have drive to do things. I cannon enjoy things i used to enjoy; everything is plain and grey for me. I do not have adrenaline rush, cannot get angry - cannot be in a good mood (when one wants to lough). I still have low sex drive. I tried Maca powder about 150 gram in a week Brad King brand. It did not make me feel any different."
Wow does this sound like an issue with Dopamine. I had alot of these symptoms and L-Tyrosine was the big help, especially the 'grey'. Thyroid hormone is also required to active Catecholamines (like Dopamine and Adrenaline) which could also be a part of it. While it's obviously your choice, building up some L-Tyrosine for a few weeks may help. A great book (if you ignore the silly title) "The Edge Effect" explains neurotransmitters well.
