Huge glass in the AM before work, two 32oz blender bottle type bottles full during the work day carried in my lunch bag, couple big glasses at night. Gets to 128oz easy.

I take a few 500ml thermos flasks to work, rather than one large one (well, I take those too but for water)
The small flask fit easily in a lunch box, easy to drink from (I dont use a cup) and having more than one means each stays cold rather than progressively getting warmer from constant open and close
Insulated bottles. I am partial to Yeti since they are also dishwasher safe.
Yeti or Hydroflask could work. Starbucks has some good insulated bottles as well
