I also wonder in rereading your post.... the doses you are relating seem odd to me for clonidine.

Clonidine oral starts at .1mg, .2, and .3.

When my son was on his ADHD Ritalin he took clonidine for a while, at 1/2 the .1mg dose, which was .05mg. At age 11 he was very sedated by it. I finally gave up with RX drugs for him and
went the natural route, as Chemar did also, and both of us found more improvement, that way.

The main thing that helped my son was essential fatty acids.
Eye twitches respond to fish oil, for many people, as well. Not all twitches in the eyelids are tics, some are just nerves that are irritated. The blinking types are more tic like, and the fast twitch that flutters is not likely to be a tic but a muscle fasiculation.

This is my EFA thread. Today it is so much easier to supply EFAs in the diet, and the dreaded toxic transfats have been removed in many foods. But back then a decade ago, we did not have these luxuries.

Kids with Tourette's respond in different ways to EFAs, so do read the book Chemar suggests.
My son is now 30 and made it thru college and has a good job. All resulted when I took him OFF the Ritalin! (and clonidine).
