drinking water
I know it's hard this early out but you have got to get your fluids in to avoid dehydration and potential kidney stones. Never had a kidney stone pre-op. It was around my 4 or 5th week post-op that I got my first one.
Does the nature of your job make it difficult for you to keep sipping away throughout the day?
You must keep sipping. If it is uncomfortable for you try different temps. 3 years out and I still don't do fantastic with really cold liquids. Love hot. Drinking some room temp water now. I got used to it.
Don't let yourself dehydrate. It's no fun. Kidney stones are much less fun than that.
