Severe nausea and food sickness (Bup SR 200mg)

I’ve been on bup for awhile, usually take XL but I ran out for awhile so for a month or so maybe even just a few weeks I’m unsure , I had none. Got some finally but it’s SR this time. I have morning nausea as is but since I took this pill it’s been amplified. I can’t eat at all, for a good 30 min I’ll have to try to not puke or fight the nausea.

Otherwise I can focus again actually and it’s cool! But it’s been making me so deathly sick it almost feels not worth it. Does open else experience this? Would asking to lower the dose help? I just don’t wanna drop bup but like the sickness I’ve felt is insane. And it feels a bit like a wax film is over my brain.. kinda here but not.
