You should give etizolam a try. I've been using it now for 3 months+ every day and have not had to increase my dosage. There are also days I don't dose at all with no negative effects.
I also use stimulants and find myself helped greatly by the use of etizolam - this is still a side gig though, I think I'd still be looking for some anxiety relief despite the stimulant use. I was prescribed klonopin for many years at 3mgs a day, and when I quit suboxone I also quit the benzo's. I have not returned to daily use, although I've got close to taking 1mg of klonopin a day at points, then once I found the etizolam I was capable of switching completely over to it. I'm talking a good few years between benzo use, I have no will to return to being heavily medicated without any help towards anxiety relief. I felt left alone once I realized my doctor would just keep prescribing them, even after I asked him for a different benzo, I was just given a higher dose.
Anyway, as I had said - I noticed that I have no had to increase my dose and the effects have remained the same. I've also tried flubromazolam, it helps as well but not nearly as much as etizolam. I find flubromazolam is better to 'knock you out' if you need it. It's a heavy drug, and will just make you pass out. I'd much prefer a few soma's for such a thing then taking the flubromazolam.
I hope this helps & good luck.
P.S. - depending on what state your in, I believe it's mainly still legal (etizolam) so you should have no problem getting access to it. Be ware of those companies over selling their product and cutting it though, I know the etizolam I get is pure, and people have told me they've taken 2-3x as much without the same results from other labs/vendors. Purity of this compound is a must with researching.
