So, how much you *should* drink has a lot of answers. I'd start with 64oz a day and see how you feel, but that's just me. When I was working towards weight loss, I do think that drinking water helped, but not from sheer ounces. If I was feeling hungry before a planned meal or snack, I would drink 12-16oz of water first and see if that helped before giving in to a craving. Often, it was enough to distract me until I was ready to eat as planned.
As to how to get more water into you, I definitely have thoughts there. When I was pregnant with triplets, the goal was to drink a gallon a day because you just need more water for your body to properly refresh amniotic fluid, maintain increased blood volume, etc. Considering that there were three people taking progressively more space in my abdominal cavity, it was *hard*.
The first thing I did was get myself a 64oz water bottle with a straw. I knew I needed to have one filling done by lunch and then half before I left work for the day. (If I let too much go to the evening, then I was peeing all night, even more than baseline pregnancy peeing.)
That bottle came with me everywhere as did my phone with a water timer. It would chirp at me every 5 minutes to sip. After about 2 weeks, I was able to ditch the water timer. Drinking regularly had become habit at that point and I was taking the sips without needing the reminder. The human brain is incredibly good at creating autopilot settings once you've started building a habit.
I don't mind the taste of water, so that part I would be giving the same advice I'm sure you've read elsewhere (water flavoring packs, brewing an herbal tea and drinking iced tea instead of water, etc).
And, yes, you just have to accept that you're going to use the bathroom more when you're well hydrated. Again, you get used to it faster than you'd expect.
