I use either a 32 ounce cup that I will drink from at home (mornings before work, evenings and weekends) and I have a 50 ounce bottle that I drink from at work. My rule at work is I have to drink at least one bottle and re-fill it once before I leave for the day. I try to drink the second bottle during my drive home from work (sometimes, it is a race with the devil to get home to the bathroom).
When I get home from work, I wash my face, change into yoga clothes and fill up the 32oz cup of water to drink during/after yoga/meditation and have through dinner. I switch to herbal tea after dinner because I like hot beverages.
Taking the supplements helps if you drink lots of water with each supplement. If it's killing you, add some Dasani drops. I like the pineapple/coconut and the mixed berry ones
