I drank about 3 cups a day of the strong espresso kind and was the same in the morning. Recently spent 5 days in hospital and the coffee was so bad I refused to drink it, have given up for about 3 weeks since i got out. The urge never goes but if I start I can't settle for one a day.
I gotta say I do sleep better and have not told the morning cleaners at work to f... off for a while now :)
