Hi,
I've always been one of those people who's had greater difficulty in feeling sleepy at the "right" time i.e. 9 to 11pm. Instead, I am wide awake and would literally force myself to go to sleep at midnight yet struggle to get up at 7am and feel sleepy between 2 to 5pm :( despite waking up early, never having drunk coffee, not eating much or any sugar in evenings, even tried exercising during the day but that still doesn't make me sleepy at night (only makes getting up in the morning even harder!)
Any tips/supplements. I do envy those who get the urge to go to bed at 9 or 10pm-ish.. I never ever have felt it. Even if I go to bed, I'll be lying there awake for over 30 minutes.
