Lee Ann...
Congratulations for deciding to quit that lousy, stinky, no win habit. No, I'm sorry, I have not heard of that Welplex Center..but if I get time tomorrow, or later tonight, I will do a search, and look it over. I would tho, (if I were you) mention those 2 meds to your Dr., before your surgery date.
One thing I do want to say is, you will succeed ONLY if your motivation and desire to quit is GENUINE, 1OO% truly inside of you! Patches, gum, inhalors, all of that, don't MAKE us quit, they are only an aide to help make things a bit easier for us when we do quit. (I falied many times too, with the patch, gum, classes, you name it!) It was only when I decided in my heart and soul, that I was 1OO% committed,...willing to do anything to quit for good, was I able to actually do it! It's really (only) what's in our MIND that makes us quit for good!
My best wishes to you,...I hope you are ready, and I do wish you ever lasting success!
