From my personal experience, stretching them out seems to make the withdrawls worse. Depending on your dose and length of time that you've been on them, just quitting cold turkey and enduring those symptoms for 4 to 5 days would get you over it. Every situation is so different. But what remains the same is you will feel, look, act, and be so much better without the constant pills in your system.
I have been on them for years and weaning myself off just recently has worked well so far. I was at six 10mg Norco a day for years. I dropped to four a day for a couple days, then two a day for a couple days and then one a day for three days. Your body will withdraw some during the reduction but it helped me get prepared for the complete stop. I tried cold turkey and couldnt do it. Good luck to you
