Powder keg...just an fyi. I had back surgery in October 2012. I had been diagnosed with DDD at the age of 37. So I had a partial discetomy, with right vs bilateral laminectomy. Bottom line, I had a HUGE pain pill addiction. When my first back surgery failed I was set to have an l4-l5 fusion. BUT decided to have WLS instead. I was sleeved in May 3013. And in July 2013 I detoxed off of the pain meds. Now 4 months after surgery I am off benzos, opiates, antidepressants and my BP meds are cut in half. I have backpain after I ride the bike but I rest a day and im ok. There is a light at the end. My feet dont hurt either in flip flops anymore. I was supposed to be on meds for the rest of my life, but turns out I was a sore back that turned addict . Taking weight off will do wonders!! Good luck I remember how hard waiting is.
