Actually you may feel a bit of uneasiness, a bit of anxiousness, irritability and SLIGHT withdrawals but nothing you wont be able to handle. Just be sure to follow Dr's orders, DONT take more than prescribed.
With that you should be okay.
@Bonestructure - Tramadol (Ultram) is NOT an opiate however it does bond to the opioid receptors in our brain which makes this the closest thing to an opiate analgesic. Its not a narcotic and not scheduled as one. Look it up.
Hope that helps F.A.B. ~Micki
