I've scheduled the Heller Myotomy for early February. I'm not thrilled but I think it's my best option at this point, given my fondness for solid food.
I talked to the surgeon. He says 80% of patients feel their situation is improved and that the benefit could last upwards of 15 or 20 years. The surgery itself should be no big deal, a few days in the hospital, some reduced activity for a while. I just hope the results offer some years of relief.
