Hi Deanna, just registered to site to see if I could gain help for my son's Tic's. Read your post about Mag. Calm is very good and does work for my son, but we have recently gone to a liquid mag found at our health store called LifeTime Vitamins - Liquid Magnesium Blend Orange Vanilla. I think it works better than Calm does. Its a bit chalky, but I usually mix it with 1/4 cup of orange sherbert and he drinks it right down. Hope this helps.
