I have started taking garlic tablets EVERY DAY Because in the past I have had over the period of 2 yrs flashing bright lights, like lightening) in front of my eyes. Even when I put my head under a pillow I still saw them, and it was very scarey. I went to a nuerologist and had a cat scan of my brain, his conclusion was' he said I have the side effects of a migraine with out the headaches. Well, since taking one garlic tablet every day, I am very excited to say, that I have had NO problems for about 4 years. So of course I told the Doctor. He didn't say much,I guess he was skeptic.
