I understand your concern.
As per your description, cyclobenzaprine doesn't produce any significant withdrawal symptoms even after abrupt stoppage in most of the cases.
Possible less common withdrawal symptoms may include drowsiness, dry mouth, nausea, headache, and malaise.
However it's good to taper off gradually if you are taking it for long period of time.
Half the dose (by cutting the pill) every 3-4 days before stopping.
For now, you should start taking half the dose of the tablet, reducing again by half after about 4 days, and again halving it after that, and so on.
You may take the OTC drugs like Advil, tylenol to control the pain.
Feel free for further queries.
