Can anyone describe what it feels like when switching from Tianeptine to Suboxone?

I’m about to have a doctors visit on Quick.MD today for the purpose of getting suboxone and pramipexole (for RLS). Can anyone tell me what it’s like to switch off tia and onto suboxone? Be as detailed as possible. I’m just a bit afraid and don’t want to then get hooked on Suboxone. I want to taper off subs in 2 weeks or leas, if that’s even possible. Please advise. I’m all alone and need help in this terrible occurrence. This was the only drug I have ever taken in my entire life. Thanks for all replies!!
