I had a very similar experience. 3+ cups per day minimum for over a decade, phased out over two weeks with no withdrawal at all. Didn't drink coffee for the better part of a year looking for a benefit.

Also noted no improvement with my psoriasis, no increased alertness, sleep felt the same, and actually gained weight over that time period.

I'm happily enjoying coffee daily again.

There is peer reviewed evidence that caffeine increases your metabolism, so it would make sense that you would gain weight after cessation. I’m in a weight loss phase and have upped my caffeine intake for that reason.
