Hydrocodone will probably do you fine and if you do not have the propensity to abuse, you will not have any problem following the prescriptions orders.
As far as taking too much tylenol, there is sufficent evidence that if you are taking even 2000 mg/day for a long time, you can irriverseibly damage your liver and basically die. The doctor will be required to test your blood on a fairly regular basis or change your prescription to either a formulation of pure hydrocodone which can be had at a compounding pharmacy, at that point the doc can prescribe amount up to 100 mg of hydrocodone with no tylenol because the pharmacy makes the compounded pill on site.
Another option will be the obvious, percocet/combunox the first is oxycodone/tylenol and the latter is oxycodone/motrin, that is a much stronger medicine than hydrocodone but if you are going to a pain doc, they have a much larger arsenol in their possesion and can try differing amounts of morphine/ dihydramorphone/oxycodone/hydrocodone/fent
anyl, and there are truly many others!
Always remember, let the doc be the doc when going for pain treatment and always be receptive to their method of treatment, don't just allow them to do whatever they want but if they seem to have a real plan of care in mind, let them do their thing and see if they are helping. You are the only person that will know if it is working but they will know too if it is not working and if you end up using all of your prescription medicine too soon in the month and need higher quantities each month, they will flag you and cut you off as fast as your hed can spin.
If you are prescribed narcotic pain medicine, use only as prescribed and all prescription say: "as needed for pain" not every x hours and dont miss a dose.
Good luck and hopefully we can help you out along the way,
