Newtothis,
I totally understand how you feel. I've gone through this few years back when my then 3 yr old son started his eye blinking to all sort of body movements. I had a video of him and showed it to his neurologist. He was dx OCD tics at 4. I was devastated and researched obsessively online for alternative treatments. I took him to an integrative Dr. and started some vitamin tests. I stopped after few visits as the costs were getting too high for me to handle. Since then I started him with multivitamins with strong B complex, extra vitamin C, calcium/magnesium, and recently I added inosital, flaxseed and GABA. I try to keep his diet clean and stay away from preservatives, artificial stuffs, and limit his sugary food...it's hard with little kid but I do give him icecream and candies once in a while, just not everyday. Now at 6 his symtoms have not totally gone but fairly mild. It did get flare up when started 1st grade few months back, but seems more OCD issue than his tics. I added inosital, flaxseed and GABA, I see a big improvement in reducing his OCD symtoms. I've also noticed his immune system gets stronger over the years, he hardly get sick anymore. He use to be a super shy kid, now he's a talkative, outgoing happy boy.
My son use to have teeth grinding problem at night also, it has stopped after I give him calcium/magnesium right before he goes to bed.
Just letting you know that things will turn around. Wishing you the best of luck!
