I took Hydro 10-5's, 4 per day, for almost 9,000 pills and quit cold turkey because they didn't stop my pain AND the pain is still about the same. Addiction? I only felt a little uneasy tummy after 8-9 hours after taking the pill. 2ndly and more important was my Restless legs, RLS. My RLS began after a transfusion.and then total confusion as i thought i was having convulsions from not enough Hydrocodone anyway within a few weeks, no help from my Neurologist Doctor who fired me, my wife found RLS on the web and a VA Doc agreed with finding and gave me RLS meds. The meds worked good, but it's almost an addiction because you have to have them every 6 hrs...or else. Well, another VA Doc said your very anemic and put me on 3 iron pills per day and WoW no more RLS. Still livin w/the pain, but WTF.
