Suboxone can be helpful, but only if you stick to low doses. You said the 8mg made you feel great so you upped your dosage right? At low doses they help facilitate the release of neurotransmitters, which can help you but if you up your dosage you’re putting your recovery at risk. At high doses they block the neurotransmitters. You’re within the recommended dosage, if you’re upping your dosage of suboxone to chase a high, it’s important to know this drug won’t give you that effect, it’s a low level opiate. If you want to get rid the high that could accompany suboxone, I’d recommend talking to your doctor about narcan or naloxone so you get the treatment without the high.
