Yes yer body gets used to it and you don't end up going as much!

As for tips..

1. Use a straw!!! Easiest way. Suck it down while your on the comp, watching tv, driving..ect

2. Drink atleast 16oz with every meal

3. Use a 32oz cup, that way you can make sure your drinking enough and don't have to count oz and keep refilling it. You'd only have to fill it up atleast twice. 3 times is best though

4. Eat hot foods, like with pepper..lol you'll crave water!

5. Exercise!! Best time to drink water!
