I have been on suboxone for about 3 years now and the first year was fine but now it's making me feel worse and worse. mostly my body temp is very off?

Not uncommon: Alterations in feeling your core temperature shifting with Suboxone is a relatively common side effect. It'll go away as you continue to be on the medication.

NOT SURE: Not sure about this have never had anyone complain after 3 years. Hopefully you did not get something laced with an opiate. Keeps work even years after starting. Eventually want to work on tapering off.
