I have had undiagnosed back pain for 10 years now and have had a fusion at L5-S1 that did nothing for my pain. Over the years, I have tried opiates off and on for pain control. Though they do help the pain somewhat, I'm afraid if I use them on a regular basis, I will become intolerant to them. I have read that with the lowest dose of an opiate, one can use them for many years and they don't lose their effectiveness. Right now, I take them sporadically -- some days on them and some days off. I can't take them too soon before bedtime, as they keep me awake if I do. Please tell me about your own experiences with opiates -- whether you take them on a regular basis, what opiate you take, what schedule you use, etc. Right now I take Hydrocodone 5-325 as needed, with no more than four pills a day. I would like to use the pills every day but am afraid of tolerance buildup. Thank you very much for your own insights and experiences.
