Has anyone had the problem where you feel more productive late at night than you do during the day? I've been like this for a few weeks and I have to stop myself from working and force myself to go to bed. I listen to some meditation to help me fall asleep which works a treat but the cycle repeats the next day. Could my circadian rhythm be out of sync? How do I overcome it? Has anyone got any tips that they could share with me as it's getting ridiculous. During the day my mind is blank and I hit a brick wall constantly with work. I can't even remember how to do things - things I've done for years on end. All ideas welcome - thanks in advance ADHDers!
