Morning Andrea!
YEAH!!!!! 2 pounds!!! You are on your way!!!
I am not sure about the calcium thing. I know you can get it in your foods. Broccoli, kale and cheeses. There is also a little in creams.If you are looking at calcium intake just for losing faster, I would wait. You just lost 2 pounds in 2 days! How much faster do you want to go?! lol
Are you taking a multi vitamin, too? The only ones I found w/out iron are the senior vitamins, but they are great. That will probably help with the energy thing. And just wait... between day 3-5 (generally) you will all of a sudden get a surge of energy and you will be zooming past dh with your cleaning supplies and leaving him in the dust!
I didn't get any headaches, but my friend did when she started from the caffine w/drawal. I usually only get headaches when my allergies and sinuses kick them off.
Hope you have a blessed day!
