@lioness Try to keep track of your calcium intake and on some days you may not need that second calcium supplement. Too much calcium can cause Hypercalcemia. I use myfitnesspal on many days since I am trying desperately to lose weight but it also tracks other things such as calcium. It even has my calcium/vitamin D supplement in it!
