I have chronic and severe sleep issues - they're probably psychological but I've subscribed to a theory of being "non-24" for some time.
I've sworn off caffeine twice in an effort to regulate my sleep better and neither time has it helped me in getting to sleep. What it does do is in the "morning" [ie when I wake] make me more alert, I'm not in caffeine withdrawal, I feel better.
If you're going to try it then my advice is to ensure you still drink enough: substitute caffeine drinks with water for example.
For me going cold-turkey it takes about 1 week for the severely painful headaches to stop and for me to be able to think clearly again.
So far as I can determine caffeine has potential long term positive effects, doesn't have lasting negative effects. I slip back in to it because it's in the house and at times I have to use something to wake me up when I'm sleep deprived. It's pathological.
