I am having a VERY hard time getting in all the liquids I need!

Does anyone have any suggestions. I sip nearly all day and I know I don't get nearly what I'm supposed to. I'm 4.5 weeks post op and If I drink too fast or even too much I feel like I have to bring it back up. Any suggestions would be great. Thanks
