Hi again,
I take Ambien too (20 mg per night) and don't think I would ever sleep a wink without it. I did try the zanaflex and it was a wonderdrug, but then I had a problem with my throat swelling and couldn't take it. I also can take other muscle relaxers, so it's not all that surprising.
Anyway, I don't mean to be a party pooper, but please be careful with the zanaflex. I have a friend and her husband who both use it. She takes the prescribed amount and it does wonders for her....for him, however, it has become his "drug of choice" so to speak and he abuses it. We don't even know why or what it does for him, but he always wants to take way too many and has been hospitalized multiple times for overdose from taking so much. Of course he is CP (from getting crushed between two cars working with law enforcement) and does take additional pain meds, but he would seriously give up oxy to take a zanflex any day.
Just be careful, please. It's a good medicine if taken correctly and my friend gets really good relief from it, but I wanted to caution you about taking that one extra....never, never try it.
All my best!
