Arginine REALLY seemed to help my brain fog, I felt motivated & focused while I was taking it in September. It was a big breakthrough for me... However, I have EBV and after taking it for 3-4 weeks, I crashed in October. Fatigue, very bad inflammation...bedridden. I think the Arginine - Lysine balance was out of whack, and the EBV virus was re-activated. Is there a way to take Arginine without this happening? ie, if i take a multi-amino, or additional Lysine, can I avoid this problem?j Is there another way to raise Nitric Oxide to get the same effect? I take Citrulline, but it doesn't have the same effect. thanks.
