I am about to buy these from Health Post and save $7 on what I last paid from another health shop!!! These tablets are truly amazing - as soon as a tension headache or tight head from stress or worry starts, 4 of these little pills and about 10 minutes later, you can feel the tension easing. I take another 4 tablets half an hour later and it is enough to get full relief. They are little tablets that dissolve in your mouth and the container is small - so convenient to take anywhere and everywhere!!
