Please keep taking the suboxone..
1. Taking Suboxone Too Soon for the First Time
Buprenorphine (the active ingredient in Suboxone) has higher affinity for the opiate receptors in the brain than opiates of abuse (like heroin or OxyContin, for example).
What this means is – if you are on an opiate drug and you take Suboxone, the buprenorphine in Suboxone will flood the brain, kick out the opiates from the opiate receptors and then fill and block these opiate receptors.
Buprenorphine only partially activates the opiate receptor, unlike regular opiates which fully activate this receptor, so when these receptors are suddenly filled with buprenorphine instead of the opiate they were filled with only moments before – the net result is a sudden and dramatic loss of activation of these opiate receptors. And it is when these opiate receptors do not get sufficiently activated that we experience opiate withdrawal symptoms.
It is for this reason that you must wait until you are experiencing opiate withdrawal symptoms before you can take your first dose of Suboxone. Once you are experiencing opiate withdrawal symptoms, many of your opiate receptors in the brain are already insufficiently activated, and taking Suboxone serves to increase this activation, thus reducing the discomfort you feel.
In other words the discomfort you are feeling is the opiate receptors that the subutex knocked the loperamide off and is now only partially activating, as these begin to shut down you will feel better as you are.. Just hang in there

I would say about three to three and a half days from when you started the suboxone you will start to feel dramatically better.
