Vitamnis and calium

I am 3 1/2 weeks out. I was wondering how everyone was doing on getting your vitamins and calcium in during the day? I am having problems getting it all in, especially the calcium. I have the calcium and vitamin chews from Bariactric Advantage, but the calcium chews are only 250 mg. That means for me to get in 1500-2000 I need approximately 6 a day. But it is too much. My tummy won't hold that, meals, and protein drinks, plus water. So, how do you recent sleevers get it all in and how? Any ideas would be appreciated.
