I am still using my store brought guard but have been seeing the chiropractor. The master herbalist there has suggested I try a vitamin/herb blend pill called Nutricalm but I cant afford it...$30. She also said to try calcium magnesium pill. I bought it today and have been researching it on the web. Apparently it has helped A LOT of people.

check that website. hopefully that works. it has a lot of people posting on their experience taking it. I would check with drug interactions before taking it though.
