How do I descale my Keurig with CLR?

After my Keurig stopped pumping a full cup, I read the manual and realized that I was supposed to "Prime" it approximately every three weeks and "De-scale" it every three months or problems like mine would arise. I'm the dummy that skims through the manual rather than reading it thoroughly, as advised, or these things would've been done. LESSON LEARNED. I primed my Keurig numerous times, but that didn't work. Unfortunately, I can't find undiluted white vinegar, even at organic stores, so I had to use 4% and 5% diluted. To no avail, I de-scaled it three times as well and primed it after each de-scaling. It brews a full cup every so often, telling me that something is working, but I need something more potent. As I've looked on Google.com, Yahoo.com and Fixya.com, I'm seeing alot of responses saying not to use CLR at all, but moreso I'm seeing that others have had a lot of success with it as long as water was cycled adequately afterwards. I'm the only one in my house that drinks coffee, so I'm going to take the risk and try it. CLR is my last resort before I do what the manual says and call the comany (Like how I know that manual like the back of my own hand now?). I know this question has probably been asked numerous times before, but there are just too many answers to sift through and the ones I've read don't answer what I'm asking. My problem now is, I don't know how much CLR to use, how diluted it needs to be, do I follow the "De-scale" process with CLR instead of vinegar, etc...can someone please give me directions on how to go about the CLR process so I don't screw anything up?
