You should be careful with that cimetidine, you're doing 2x the daily maximum and in general it's linked to man boobs with longer term use. I think just 400mg of it you'd experience the potentiation desired for your opiate. Do you also find the need to mix in 2 anti-nausea meds? I feel like the bud would give you just as much help even if it's just the cherry on top.
Damn Burnt I randomly blacked out (passed out really) off 10mg the other night, I'd has 25mg Diazepam and 400mg L-theanine though and 1 diphenhydramine capsule. It happened in a snap though. I normally never take Ambien, I just found a few lying around, there's 2 and a half of them left. I did black out maybe once or twice/pass out but the difference is I'd opened a bunch of stuff on my laptop after it was already turned off and was typing random letters in notepad+ but it was mostly thousands of paragraphs being made from falling asleep on the space bar.
Either way:
25mg diphenhydramine (mostly for ear fluid lately)
1.8g kratom (nighttime maintenance dose, not for feeling much but stopping RLS since I only dose in the afternoon otherwise)
15mg Diazepam
400mg L-theanine
3mg of Ambien (failed to split that tiny 10mg 50/50 and just took the smaller half)
30g of Lewena kava
300mg Gabapentin (tapering)
And lastly some hits from my dab pen
The dab pen and weed in general will always carry, but mixed with kava they're too good.
