I manage to eat a Weetabix on a little spoon like a baby , but I ca n't taste it at all . The eyedrops help alot , so I have a few of those and tape some gauze over my eye to keep out the light . After tossing and turning , every way I lie causing me pain , and I eventually pass out at around two am . Tuesday . I got up this morning and was happy that I 'd been asleep - until I realised the patch on my eye was there and remembered my face .
According to the above context, answer the following question.
Why did the writer pass out at around 2 AM ?


Because they were tired .
