i got this bottle a little under 2 weeks ago and i'm already in love with it - design and function wise!! prior to getting this i was almost constantly dehydrated because of my own mental blocks and inability to remember to refill my smaller water bottles. now that i have this bottle and since it's a full days worth of water for the average person, i now have no problem drinking enough water in a day. just fill it up once in the morning and set a goal to finish the whole bottle before you go to bed and you'll start to feel more hydrated quickly. i mean like i mentioned i've only had it for just a bit under 2 weeks and i already feel more hydrated than i have in my entire life, and i'm genuinely not exaggerating about that. also the nice shiny design catches the attention of my ND brain a lot so it reminds me to drink water when i see it, even if i'm [rarely] not using the bottle itself.
