For almost a week now, I have been completely exhausted every day. No matter how much or how little I sleep I get, I still end up having a 'sleepy' headache and don't feel like doing anything. The past couple of days I've given in and taken short naps, but that still doesn't make me feel any better.
Any suggestions on what might be causing this, or what I could do to prevent it? Its really starting to get to me
