I suffer with asthma as well as Fibromyalgia and Hypothyroidism. I came off Pregabalin because I put on so much weight whilst taking. I had previously tried Gabapentin which made no difference whatsoever. I was then prescribed Tramadol which does help with the pain but I have gradually weaned myself off it because it depresses my breathing. I use inhalers but no matter how hard I try to inhale it feels as though my lungs are only working 10%..... I looked on Google for Tramadol side effects and one of the side effects is slowing down or STOPPING breathing. Has anyone else experienced this on Tramadol? My breathing has been so much better since I've come them!
