hi again

increased tics from milk usually is a result of lactose/casein intolerance which a number of TS people seem to have, along with gluten intolerance. But if you arent dairy allergic it shouldnt be a problem. My son drinks a lot of milk with no adverse effects on tics

re the extra calcium...if you get enough in diet it isnt usually necessary to supplement extra. the theory is that it is primarily magnesium that TS people are deficient in ... here is some info on it from Bonnie Grimaldi herself:

it is believed that magnesium taurate is best form for those with TS tho my son has always taken his magnesium and taurine separately (he uses a blend of mag citrate and glycinate)

mrsD has an excellent thread here on Magnesium
