How much are y’all able to drink?

I am 7 weeks pregnant and SOOOOO nauseas. I can barely drink a 16 oz water bottle in one day. I fear I’m going to become dehydrated especially if I start puking. How much are y’all drinking and if you’re drinking a lot, how do you do it while nauseas? 😷 I wish my fridge had an ice maker because I think eating ice would make it easier
