Insomnia

For at least 2 weeks I haven't been able to sleep. I have never had this problem before, as I can usually fall asleep on command, and stay that way until at least 3 crows of my rooster alarm clock. I think all the stress of the stones and the last IVF cycle may have me a little out of sorts. I will try to stop napping when I get home, although I don't do that terribly often. I fear to even think this horrible thought, but, maybe, I need to lay off the coffee for a while. I went from about 4 cups a day before the cycle to 1 half calf. Now I am creeping back up to about 3. Could this have anything to do with my precious sleeping pattern? I am forced to consider this.
