Legitimate. This is a note I sent to Kevin telling him of my experience with this.

Here is what I do when I take a break. I take ultram everyday and I get ZERO withdrawls. But....... and it's a big but. LOL. One time when I took a holiday from norco I took way too much of the ultram due to my pain and after about 4-5 days I went back to the norco and it didn't do a stinkin thing. The next time I took it easy. 2 pills everytime I felt pain or withdrawls might come. But no more than 8 a day. By day 7 I was down to 4 a day. On the 8th day I got a new prescription of norco and let me tell you they worked unbelievably. Almost as well as the first time. kid you not. So I hope I was some help to you!!
