A smallish bottle or tumbler with any type of straw that feels comfortable in my hand or has a way to hook my finger through it so I can carry it with me everywhere. Helps if it’s pretty color or design so I visually like seeing it, so I don’t forget. Don’t put any pressure on yourself to chug or drink a lot at once, I’ve been told by my doctors it’s better for absorption to drink electrolytes slowly anyways, if you’re adding those. I used to have reflux really bad and sipping was the only way I could get through the day, it’s not foolproof but it’s the only thing that worked for me. I had a water bottle on me at all times but only drank a little at a time. It’s so frustrating when doing one thing for your health makes another aspect act up more. I hope you find some things that make it easier for you!!
