I've recently discovered iced lattes (everyone else has probably been drinking them for ever) but I was recommended to try something with caffeine in addition tofrom my usual water to help with some meds. But good lord they're expensive.
I work 9-1 and would like 2 in that time but don't have access to a fridge or freezer. I have a kettle. Obviously I could drink coke or tea, but I just liked this and am trying to work out if it's doable but a 5yo that doesn't sleep is not conducive to problem solving!
Also is instant coffee likely to work or do I need ground?
