I am struggling to stay awake and need to not do ths at work so am thinking about caffeinated drinks.
I don't drink coffee and the tap water at work makes me ill so I can't make a tea. I already take a flask of cold water with me.
I don't want to drink carbonated drinks and I can only drink lactose free milk so can't get one of those lovely chocolate milkshakes.
Is there a drink I can have at work that fits the bill and will wake me up?
