Yet another false start to the day

Last night I hooked myself up to a sleep study machine which is to determine if I have sleep apnoea (apnea) and it was not as uncomfortable as I thought it was going to be, nevertheless I still had a restless night. The little portable machine which is no bigger than a small cassette player was strapped to my upper abdomen, with a nose cannular to monitor my snoring (yes I snore) and a small monitor attached to my index finger. When the preprogrammed device came on my finger lit up and all I could think of was ET phone home. Every time I woke up during the night I checked my finger to make sure my light hadn't gone out (heaven forbid my light should go out). The day started out with the same plan as I'd had for the past week, to go and have a fasting blood test but due to whatever is going on in my head I again had another severe headache. The last thing I felt like doing was driving to pathology to be drilled for blood so I had a cup of coffee instead and then it happened again, my headache began to clear. I've been a sufferer of migraines most of my life and coffee is the last thing I would have but at the moment it seems to be the cure for these bad headaches. I haven't been able to figure that one out so I emailed my doctor this morning (yes I have a progressive doctor who would rather answer my quick questions via email than to waste my time and his by coming in to see him). His response was, "Still get it done and fib (with my blessing) i.e have your cup of coffee". So if it happens tomorrow morning I will have my cup of coffee and look the nurse straight in the eye and tell her I've fasted for 12 hours with nothing but water to drink.
