I've tapered to approximately 3mg every 8-12hrs and still experienced the classic withdrawal symptoms. Starts with sniffing/sneezing and yawning for me. Then restlessness, chills, sweating, diarrhea, etc. I've never found a painless way to detox, even with extensive tapering, but it definitely helps. The lower you jump from the less intense and less prolonged the withdrawal but it's still gonna be there, especially for long term users. After a decade+ of opiod use my brain does not know how to function effectively without it. The lack of motivation, depression, and anxiety are worse than any physical symptoms for me.
If you have some gabapentin or benzos they will help a lot. Look up the Thomas method for supplements that make a difference, too. Depending on how long you've been using, this time and overall, it may not be as bad as you're expecting but definitely make sure you have a few free days to recuperate. Gentle exercise, hot showers, and staying hydrated will make things a little easier, too.
