Since I can remember I have always drunk diet drinks had sugar free sweets and other food products. About 6 years ago I experienced severe fatigue, loss of feeling and tingling in my fingers and down one side of my body. I even experienced paralysis in my legs. I was sent to see a neurologist and he put me through lots of tests suspecting that I had MS. All tests came back negative. My Mum then met a lady who had MS and told her about Aspartame. I then cut it out of my diet completely and my symptoms disappeared.
I have been fine since.
