Sorry Hillheader, misread your post.....I thought you said medication as opposed to meditation.
I would still talk to your Doctor and/or a counsellor and see how they can help with the anxiety/panic attacks. I was getting panic attacks on a daily basis middle of the night, any time in fact - it was out of control.
After 3 months of counselling with a variety of 'professionals' I have managed to get back on an even keel.
To help me sleep I take MELATONIN, which is a natural sleep remedy. I specifically asked my doctor to prescribe something naturally occuring. This is really good stuff.
