Hi Nicola/Sian, thats interesting, I too have problems going to sleep sometimes, comes in phases, its miserable when its happening and I know that any caffeine after about 2pm impacts my sleep and its so easy to not to drink it as I know what the outcome maybe. I hope I can bring that same ease of making that choice to the eating!
Did you both feel much better for eliminating caffeine entirely? I know I rely on it to get me going in the morning (tea that is, don’t drink coffee)
Good luck all.
