Suboxone Withdrawals

Well I'm going to start with everybody's body is different. I was on opiates/fetanyl and benzos for appx. 15 years, I will be taking 18 months in the middle of January and currently working on my suboxone taper. I was on 16mg, dropped to 12, then 8mg, then 6mg, now on day 3 of taking 4mg. I feel a little tired today but maybe today is just an off day. I should be taking my adhd medication to help with the bit of energy to see if that helps so I will start that tomorrow. I just had questions for anyone else who has tapered off of suboxone as I am a little nervous. I fear that feeling of dope sickness again and know this is a possible time of relapse although I have a very strong foundation and support around me which helps a lot but I know drugs ain't hard to find. My question is when did anyone start feeling the withdrawals when coming off suboxone and how long did they last? And I'm only asking this question to those who properly with their prescribing doctors advice came off suboxone. When did you start feeling withdrawals and how long and how severe did they get and at what doses? Thanks everyone and also proud of anyone who has gotten sober on this page and who ever is even trying. Feel free to DM me if your new to recovery or even if your not and have questions! Love yall.
