I inadvertently quit coffee a while ago after a bad flu, and not drinking it for a week. What it helped me discover is that I was not getting ANYWHERE near enough sleep. I thought I was functioning fine on 5 hours, but when I didn't have coffee, I was hitting a wall after lunch. When I started getting 7-8 hours, I felt great without coffee, and I started making progress in the gym and losing more weight. Caffeine is supposed to help with those things, but it was actually masking bigger issues for me.
