I suggest you wait AT LEAST 24 hours from your last DHC/Tramadol dose before taking suboxone, if not longer (36 hours). Im no doctor but this information is readily available on the manufacturers website. As you have already discovered, precipitated withdrawals isnt very nice so its definitely in your best interest to be especially prudent and wait as long as you possibly can.
Anyways. all the best on your journey.

You are supposed to wait until you are feeling the withdrawal symptoms before you start on the buprenorphine. Can i ask why you are swapping from 1 to the other?
I'm sorry but we cannot give that information here. You are going to need to work with the prescribing doctor to do this properly and safely. Best of luck. Let us know how you are doing.
