I'm having an MRI done on my right knee this morning. I'm seeing my ortho dr this afternoon to go over the results to figure out what needs to be done. I'm a cashier and stand on concrete floors for 40hrs a week for the last 28yrs. My goal is to retire when I hit 30yrs but need/want to get all my health issues taken care of while I still have good insurance. I'm using Chantix and get that FREE through my insurance, how great is that! I'm 7hrs into day 2 of my quit and feel a bit foggy. I'm sure that's to be expected. Whatever the outcome of today's doctor visit is, I WILL NOT SMOKE! It helps to know you are ALL rooting for me! Thanks for that and wish me luck!
