What size water bottle should I get?

32oz is the sweet spot — three fills = 96oz, nearly your daily target. 26oz is lighter but needs more refills. 40oz is heavy but fewer refills.

Are insulated bottles worth it?

Yes, especially for GLP-1 users. Cold water is more palatable (important when nauseous). Insulation also prevents condensation on your desk.

Can I put electrolyte powders in insulated bottles?

Yes, but clean thoroughly — electrolyte powders can leave residue. Hydro Flask and YETI are both easy to clean. Avoid letting electrolyte water sit for days.
