My husband has been on suboxone for 2 months now. He does not take them everyday, only when he feels the need to. He was addicted to herion and last relapsed in July (2011). From July to Aug he took methadone to help with the withdraws. Then I made him switch to Suboxone. The last 3-4 days he has not been himself. His pupils are very small,eyes are red and he has stomach problem (diarrhea, nausea). He has been very tired and "out of it".. Is he relapsing or is the suboxone making him look "high" to me???
