Hi! I would skip it if it gives you that reaction- because why create needless anxiety in your body?
I think Dr. Clark mentioned it as a natural alternative to drugs for those who may need it to rev up during the parasite cleanse.-- maybe in case the cleanse may cause some lethargy in some people. Arginine is more non-toxic than over the counter stimulants.
Still- one has to be careful as we are all not made alike.
During parasite cleanses I never use arginine! Valerian herb tea is all I need to help me fall asleep like a baby- if I need something to calm me down.
Heaven knows I don't need anything to rev me up! ;-)
