I drink a big glass of water when I wake up, then several glasses a day. Never have a meal without water and always have a small glass with my coffee( so up to 2L per day) or wi e, if i' drinking that. Had to make a real effort when I worked full time. Water affects not just your urine but bowels, as well, not to mention your skin!
Breastfeeding gets you into the habit of always drinking a big glass before every feed
( and I fed 4 children) so the water habit kicked in long ago. I always put a small bottle of (tap)water in my bag and, when exercising, drink even more.
With practiice, you can train your bladder!!
