Is it normal to have no sleeping pattern
I can stay up for days then sleep for a day, or stay up all night and sleep during the day, or sleep at dinner time and get up in the evening. If I ever have a 'normal' sleep it doesn't last more than a day. I prefer to sleep during the day but I don't have any form of regular sleeping pattern. I know this is unhealthy but I can't sleep at all unless I'm so tired I can't keep my eyes open.
