Far Too Much Sleep

I'm sleeping far too much. OK, I've been ill quite a lot lately, and over the last few years I would say. I still feel drained. What I can't understand is I'm sleeping too much. I sit down on my sofa feeling fatigued for no apparent just fall asleep. I'll sleep most of afternoon and go to bed early and still sleep and get up late. I often get fatigued, sometimes so fatigued that it hurts and I have yo ho to bed 

Like yesterday for instance. I went along for my appointment to have my eyes screened. After I went with Jack my next door neighbour to the cafe at the heathway, I felt fine. I ordered milk shake, egg and chip and slice of bread. I ate the bread and just yolk egg and 4 chips and drank my milk shake, but all of a sudden I became unwell, felt so sick and weak. I rarely have milk shake, it was s few months back i had milk shake, so I know it's not that. It happen eveytime I eat. 

How I got to the cab office I don't know. I got home and went to lay down on my side for half hour. I hadn't eaten much really. I was a lot better after half hour. This happens to me every day, with what ever I eat. I just don't understand why it happens all the time. Saying that I do suffer from various illnesses. 

I've just phoned my Dr surgery, I've got to ring 8am in the morning to get appointment with someone there.
