I've Been Drugging Myself In My Sleep

There is no other plausable explanation, but let me back up a bit.

I'm a somnambulist (sleepwalker), and have been since a child. As a matter of fact, sleepwalking is a condition that mostly occurs in children, and disappears with age. Only a very small percentage of adults are affected by it; I am one.
Generally, it doesn't prove problematic. A somnambulist will not do anything in a "sleep state" that he or she will not do while awake. I have audible alarms on all doors in my home to keep me from leaving while asleep. One of the most annoying things for me personally, has been waking up with crumbs in the bed and peanut butter all over my pillowcase. No biggie.
Sleepwalking, for me, seems to occur when I'm heavily stressed. Years ago, when going through my divorce, I was given a prescription for Ambian to sedate me beyond "walking". Worked purdy good.

Now, you guys know I've been sick, and haven't been sleeping well. While at the dok's, we talked about some temporary sleeping pills.
"You gave me Ambian years ago, but I'm wondering about that Lunesta."
My "dok" is also a neighbor, and his wife Amy, a friend.
"Whal Toni, I took Ambian...once. Amy said I woke her, wanderin' around the house, buck nekkid! I didn't remember it, but she had me sign a piece of paper, and sure enough! There was my signature, big as day!"

Anywaaaaaaaaaay, he gave me Lunesta, and I filled it along with the cough med and antibiotic. The antibiotic series ended on the 5th, and I'd already stopped taking the cough med 'cause it was giving me killer headaches.
I continued to feel "poorly", but chalked it up to gettin' "old", and not physically being able to ditch the "icky poos". What was strange was that for the last four days out of five, I've been so freakin' lathargic, I've barely made it out of bed! I'd been sleeping for hours, and was highly disoriented.

The mechanism of Lunesta-like meds is to give you eight hours of sleep, and it did, but then I would wake in the a.m., do a few things, then fall back into a deep slumber. I was having a hard time just thinking, concentrating, etc...
I called my bloggy momma early yesterday morning, remember the convo, and that I was in a really pissy mood. For me to be in a "pissy mood" is not uncommon, but for me to be talking...to anyone, on the phone, early in the morning is downright bizarre.

I took my dose last night, saw there was only one left, and made a *ahem*, mental note to call in for the refill this morning.
I felt a lil better this morning...not nearly so lethargic, and called the pharmacist. He's a neighbor, and a friend as well.
"Sorry Toni. You're gonna have to wait till the 13th. It's too early."
Huh??? What???

That's when I counted, backward, datewise and looked at the "count" on the prescription. Five pills were MISSING.

Now, no one has been in my bedroom, and that prescription has been on my nightstand from day one. The only thing I can summise is that, I have indeed, been drugging myself, in my SLEEP!
Freaked me tha fuck out!

At any rate, I'm kinda back amongst the living, and you can bet your ass, this coonass won't be "dosin" on any mo Lunesta!

Dang....
