Dua prayer request for friend 🙏

My friend is struggling withdrawal of benzo diazepines that he got addicted into by psychiatry He has taken them for five years but is tapering

I know a little about withdrawal but not benzo I have zero experience on that substance but I know it can be very harmful and even lethal withdrawing from benzo diazepines ...

He was in a lot of pain a few hours ago but stopped responding and idk what to think

Can I ask for you to make dua for him 🤲🙏 He is sunni but he was the one who opened my eyes to shiism and gifted me nahjul balaga.
