My Mom has trouble sleeping most likely related to Parkinson's disease. We have tried many prescription sleep aids with limited success. Mom's trainer mentioned that one of his other clients used Calms Forte and I noticed the reviews on Amazon are really strong so we gave it a try.... and AMAZINGLY I could see her body relax and for four months it helped her sleep. I'm not sure why but after four months it did not seem to be effective... possibly because of the progression of Cortico Basal Degeneration which she also has. But I am so appreciative of the four months of relief that we got.
