It is normal to get the buzzing, tingles, cramps, etc to some degree for the first few weeks until your body adjusts to the lower calcium levels...If it really bad, then get
liquid calcium (if it calcium
citrate, it absorbs more completely.) Are you on antiacids or acid suppressing meds? If so, this will hamper the calcium absorption a bit...Once again, if it is calcium citrate, it will absorb better because it is already "acidified"...
