I love caffeine but I made a decision five weeks ago to stop drinking it, I do feel better and I have been sleeping a lot better. I only drink it once per week now at most and I don't really miss it. I think that any study carried out on rats or mice doesn't prove much as they are not human!!

Yeah I'm all for just cutting out the middle mice and experimenting on people ;-)

I was up to about a pot of coffee per day at one point. I love me some caffeine...
