zsh/bash script to remind you to drink water.

If you're like me and you spend a lot of time programming with the command line open, chances are that you forget about everything for hours, which includes drinking water. At the end of the day I used to realise that I had not consumed enough water. Hence I created a bash/zsh script to remind me to drink water right on my command line.

1. Copy the thirsty.sh file and paste it in your zshrc or bashrc or theme, etc.
2. In your zshrc/theme/bashrc locate PROMPT='$(some_function)' or PROMPT_COMMAND='$(some_function)' for bash and add drink_water inside that function. (This will be the case if you're using a theme)
3. If you can't locate PROMPT, then just add PROMPT='$(drink_water)' or PROMPT_COMMAND='$(drink_water)' for bash in the file.
4. Set your time interval in the variable WATER_TIME in seconds, eg : WATER_TIME=1200 sets it to 20 mins.
5. Once notified, you can remove the message by simply typing not_thirsty in your command line.

Since my knowledge on bash/zsh is limited, I'd be more than willing to accept improvements and additional features in this script.
