I am 5 weeks post op from RNY. I have struggled to get all my water in. Mostly because of my drinking style. I gulp. I practiced for months before surgery to take small sips and after surgery I think I'm taking small sips but it still hurts. I'm also very thirsty since I feel full after 2 sips. I recently started using my food processor to chop ice. I eat the ice because it quenches my thirst. Today a friend told me that eating ice chips can actually dehydrate you. Is this true? If so why? I have not asked the almighty Google yet, but am headed there next.

Eating ice does not dehydrate you. However, since ice does not provide you with the amount of water necessary to hydrate your body properly, it is not advised to only have ice. There is no way to eat enough ice to compensate for the amount of water you need to stay hydrated. Therefore, use ice to keep cool. Try drinking water at a warmer temperature.

Try something like this. Doesn't it limit the sip size? It's a toddler sippy cup.
