This is really awesome to hear. For years and years I have thought I was probably just weird or anxious because if I have caffeine later than about noon I have serious trouble getting to sleep that night (bedtime around 10pm). It's nice to know that there could possibly be a reasonable physical cause for this and it's not just all in my head.
