The hospital start me on crystal light but they give me on lemon and orange that make with upset stomach. I start with other flavors none the that lemon or orange in it. So what I did was I had one bottle of 8 oz with Crystal Light and the rest of water now what I did was of the 8 oz of Crystal Light I divided 2 oz for every 15 oz of water a plain water and than I would take another 2 oz of the Crystal Light and that's how I did it so it wouldn't be so bad or heavy on the my stomach.
