Hey D and WELCOME=) I too had GB surgery in 1987. People ask...YES, I lost the weight. YES, I've kept it off. I've not had a day of wellness since...bummer.
I don't know about Baclofen, as I've never used it. There are several here who have. They'll be along shortly. Do you have issues w/metabolism of meds? I DO. The Fent patch (matrix type) did not work for me. I'm happy it works for you.
Give your doctor a call to ask about adding a muscle relaxer.
