Re: ADHD and irregular sleep patterns
Yep, like everyone has been saying, ADHD can definitely cause irregular sleep patterns. Ever since I was a kid I've always had the same complaints that you do, it takes me forever to fall asleep. Even if you do a winding-down activity first (like reading), it still could take like an hour plus. I have found that certain noises help me to sleep better, so you could look into that. Also, my doctor used to tell me that being active within a few hours of wanting to sleep can make things worse. That I have found to be true as well. You could try monitoring that for yourself perhaps.
Like others have been saying, occasional resting periods throughout the day could help too. Just try and alter your lifestyle to something that might help you be more relaxed. Best of luck!
