I have been taking an arginine supplement since around the end of March. I fully understand that this instantly qualifies me as a taken consumer who pisses away money on sugar pills to many, but I do feel that I saw results in the body composition department. That being said, I started having trouble sleeping in the summer.
After changing matresses, taking ZMA, melatonin and doing everything I could think of, I stopped taking the arginine. I've been off of it for 3 days, and have not had troble sleeping in the least (knock on wood). Is it possible that this supplement, NO2, there I spoke it, could lead to insomnia?
While on this, everything felt real tight all the time. I'm not saying that it turned me in The Hulk or anything, but to use the cliched word, I felt an extremely extended pump. My thinking is now that this prolonged effect decreased my ability to relax at night enough to get to sleep.
In addition to the "you get what you deserve" comments is there anyone who feels that insomnia could be an effect of these current arginine supplements.
