Hi, I have been taking hydrocodone 5/500 2 tabs twice a day from 1/17-1/23. I took for 8 days, then stopped didn t need anymore. I became anxious and low grade depression since stopping. Back in August 2013 I was on Oxycodone 10/325 6 pills a day. Stopped cold turkey, took 2 weeks of misery. By late Sept I finally felt normal. Any reason why the hydrocodone would cause this reaction after only 8 days? I was on the Oxy s for a couple years until I quit in August. It s sucks I have 3 Detrenritive, discs, and stenosis, scared to have surgery, afraid I will end up worse, any thoughts as to why the hydros would cause this?
