Hi...I am on Halo, 3 ed, and Cyano, 2 ed...on my last week of Cyano. I've been getting terrible cramps in the front, by my throat, and the back of my neck for a few weeks now several times a day. I am not getting any cramps in my legs or arms, some in my back but not bad. I am drinking tons of water everyday. Just wondering if anyone has any advice for me or if I just need to add even more potassium to my diet, more than already. Thanks for the advice.
