another thing i forgot to mention is that allergic reactions can sometimes make the mind race which can cause obsessive thinking. recently i was taking alot of supplements in gelatin capsules to help clear the candida and make my body stronger but i was getting very nervous w/obssessive type thoughts. i would take more pills thinking they would help but it only got worse. i found out by a process of isolating each supplement that i had a severe allergy to gelatin. gelatin contains free-glutamate which is an excitotoxin & which is the G part of MSG. it causes the nerves to become overy excited. it can kill some people who are allergic to it. it made my heart race and caused me to become very itchy. i felt like i would go insane. i have not had the crazy nervousness since i stopped all supplements in gelatin caps.
