I have utilized this patch for three days now, I was using Norco, and Soma due to a car accident 8 months ago, I tapered down until last Tuesday then quit cold turkey. All WDS hit me like a ton of bricks. I was using them as perscribed but 2 pills every 4 hrs leads to 8-10 a day if you already don't sleep. Since Tuesday morning I put the patch on and all symptoms except stomach and insomia are gone... THANK GOD. Now after 6 nights of no sleep, no energy, and flu like symtons I am going nuts. I talked to my Dr. and he gave me a three night supply of ambien for sleep, and immodium for stomach, so far everything is cool. I went through 6 days of hell, but I am starting to see the light. Had I known about the patch sooner I would have gotten it right away. Now I just need answers to deal with the pain without the meds...???
