Hey Waterbaby: I was prescribed tramadol several years ago. It seemed to work at the 100mg. for about
two months, then it gradually stopped working. I think if you've ever been on any of the older pain meds, as I had been from time to time, your tolerance may be high. That was my problem. having been in a Motor Vehical Accident and on stronger meds for extended periods of time, the Tramadol just wasn't strong enough. But, and it's a big butt, there is a threshold with Tramadol, that if crossed regarding maximum dosage, can cause your respiration to halt, ie your breathing may slow down. I can't remember the exact number but you can check package insert or call pharmacist or doctor. I did get some relief for a number of mnths. Good luck.
