RE: Coffee and Science... How they both work?

This post made me think about coffee and my I would said it ˝addiction ˝ about it. I never thought that coffee harms me, but I knew that 3 or 4 cups a day are not that good idea. I tried to stop drinking coffee for a few times, but I just couldn't imagine the morning without it.
On second question my answer would be ashamed yes. Sometimes when I drank coffee I don't have needs for eating, I just feel like my stomach already ate something. This is some very bad habit of mine.😕
