I am not sure what you describe as "twitches" but if you mean muscle twitches/tweaks you may need to supplement with Magnesium. You may be low magnesium. The better magnesium supplements are not in pill form. Transdermal (GLOBAL LIGHT sells this too also Ancient Minerals at: http://www.ancient-minerals.com
is one method and some of the Ionic forms that you mix with water are good too. I supplement my Miracle-Mineral-Supplement
use with Magnesium as I get muscle twitches easily and magnesium has always made them go away. That is my approach. Hope this helps!
