Basically I need to take a powerful probiotic and some B12 in extra quantity. He did say that Flagyl can break the blood/brain barrier thus affecting the CNS. I just wish I was told that prior to being given this. Mainly it takes time though to get out of the system and for your gut to balance things back out. I am also doing epsom foot baths now which I guess can draw the toxins out of your body. I did my first one last night and the water actually turned brown.
