Use a straw.
I don’t know why this works for me, but I will ignore a water bottle for fucking hours, but the moment I put a straw in it, glug. Immediately, glug.
People come over and are all “why do you have giant 7/11 cups on your desk” without realizing that 1) these fuckers have the slurpee lids on them which reduces spilling and adds ease of inserting straw without breaking the little plastic X of traditional lids, 2) they are huge, and maybe most importantly, 3) they come with straws.
