My sleep was being wrecked and my sleep apnea was out of control until I cut out coffee after noon and limited my morning intake to 2-3 cups. I feel far better now, and on top of better sleep, I have a bit more control over my depression and anxiety. It wasn't a cure all, but I definitely noticed an improvement. It's also probably a function of age, I think its effects became more negative and pronounced the older I got.
