@gregh286 - I am giving plain arginine (cheap) a try after reading about your experience with NO2 Black. If I have a good result without bad side effects, I will probably give the NO2 Black a try. It (the arginine) definitely does something to me, I think it's good, I have been going very slowly because I can react very strongly to small doses of things.
So I was taking 2 or 3 500 mg. arginine capsules for about 2 days (one capsule 2 or 3 times a day), doing okay and actually sleeping a little better, and then one morning woke and was completely drugged, it sounded like someone else here experienced ( I can't see their name right now) but I was drugged, no other word for it, for most of the day. So I have stayed off of the arginine for a couple of days.
However, this article may explain this reaction:
http://www.ncbi.nlm.nih.gov/pubmed/9219930 It appears to be saying (though am not sure, I'm not a scientist!) that arginine increases the effects of GABA. I take a lot of GABA stuff in the middle of the night when I have my worst insomnia. So tonight I'm going to split open a capsule of arginine and take half since I am so dang sensitive, and cut my GABA supps, and see what happens. There's definitely a connection between arginine and GABA.
The other thing that happened was today. I woke up crashed (PEM), no surprise to me as I knew I'd overdone it yesterday and took one arginine capsule. Due to some amino acids (BCAA'S) and who knows what else, I'm now recovering in generally about a day - it used to take me 3. Well, about 1:30 this afternoon I could feel energy coming back. I'm still afraid to really do anything but it seems my recovery time was shortened by several hours. And this morning was the first time I've taken arginine since last Thursday because I was so drugged on Friday.
So the experiment continues. I want to see if I can tweak my nighttime arginine dose and supplements such that I'm not a zombie the next day.
And re arginine and HHV viruses - arginine is also supposed to increase NK cell function:

http://www.ncbi.nlm.nih.gov/pubmed/9824439
so paradoxically it might actually help with these viruses, contrary to what I've heard all these years.
I am so glad you posted your experience here!
(BTW, amino acids can be surprisingly powerful. BCAA's cut my PEM recovery time in half. I did a post about this awhile ago)
