sambob ... tramadol is less powerful than hydro, and while it helped with lower back pain, it had some weird side effects- you might feel talkative, chatty, generally positive mood... but after taking it for a while (for me 2 years) that stopped. I had to take it to get outta bed, go to work, come home, etc. So short term good, long term... not something to be messed with, unless there is no other option for some reason. I have had to WD from a lot of things in my time. This was by far the worst. I only use Tram now if I cannot get my usual crutch for my back. Good luck, and what you might do is tell the doctor you did some research and ask about specific side effects. Realistically if the doc said this is all they can give you, that may have to do for now, but it does lay the ground work for you to come back to it with the doc later and ask for another option. It may be very effective for the short term, and if that winds up being all you need, awesome.
Be careful driving, operating machinery blah blah blah as you get used to it. At first it made me chatty and all then once I had increased dosage it made me really feel loopy, and not in a cool way. Dizzy, sleepy, etc. At my max i was taking 300 mg per day, and actually found that taking 50 to 75mg was more effective. But beware the withdrawls. Not a good time.
