Using Kratom after SR to cover any PAWS

Hello! Long term sub user. Boyght some SR. If this actually works i’m going to scream from the rooftops. I do know it’s getting banned though :( Anyway, i’m concerned about staying on SR too long. Would occasional kratom leaf help if i need some help after i do 12 days w SR? I’m not trying to jinx myself but i’ve been on subs so long .” I’m concerned what lies ahead. Never used Kratom but did buy some leaf recently to have. Also I heard SR blocks opiates like subs. Is that true? Doesn’t matter to me if it does my only concern is if the SR doesn’t work and I can’t take a sliver of a sub if I need it. Thanks everyone.
