"have back pain, dr. gave me this to take with norco 3xd. i didn&#039;t think it would help being &quot;non-narcotic&quot; but has taken my pain from sometimes an 6 with hydrocodone to maybe a 3 or even 1. however i have experienced withdrawal symptoms. i don&#039;t know how to detox because you&#039;re not supposed to cut them in half. anyway, if you get dizziness and like mild electric shocks in neck head when you don&#039;t take it, it may be from this drug. i&#039;ll still take it because it helps so much."
