Hi,
I have about 4-5 decaf coffees. I cant stand it black, though, so ahve been using a banana tetra split during the day as milk in each cup. It gives me something to look forward to (!)
I thought it was a great brainwave to do that, but soon had to switch to decaf from regular as I was getting a bit twitchy!
An added bonus is it helps me get more water down. I dont really like plain water, and each of my cups of coffee is 0.25 litres. I also try to get an extra 3 litres water down as well.
