Aqualert is a great app if you're on Android, it not only sets reminders to drink water, but it also will tell you how much to drink a day based on your height and weight.
I'm so glad you two are alright! For those who have a hard time remembering to drink water there are lots of apps on the google play store that remind you to drink water. Here's the one that I use!
