Ambien: The what the hell was that pill

SO as you my reader, know I have been on ambien for two weeks give or take. The first night produced hotdog bun hallicinations amoung others and from there I am unsure. What I DO know is that the night before last I ate an ice cream sandwich in my sleep, put half of it in my lavender plant and attempted to shove the wrapper down the sink drain.
The weird part is I vaguely remember doing these things but it is very hazy and other worldly.
Yesterday I realized I had not taken a tylenol for a week. Prior to that I was popping 8 to 10 a day for constant headaches and body pain. So, the sleep is helping to rejuvinate my body, but at what cost?
Last night I broke the pill in half, after all in the morning I am rested and feel better than I have in a long time as proven by less headaches and better mood. But this morning I woke at 4 am and am not so happy happy joy joy. I believe there has to be a happy medium that will allow me to sleep and wake rested without feeling either groggy (OTC sleeping pills) or hallucinating and sleep walking.
In anycase... ice cream in the lavender didn't seem to hurt it much and C fished the paper out of the drain. Lets just hoe the dead bolts work and that I can't figure them out at 2 am. Yikes.
