Welcome to SR.com. You've come to the right place
My best guess is that kicking off of 30mg/day is not likely to be especially terrible. I used to do 240mg/day OC for years. I didn't kick off that level (and wouldn't if I could avoid it) but people here HAVE, that much I know for sure. So based on this observation, it would APPEAR as though quitting at 30mg/day is, in theory, 'doable'.
Now, don't let your addict brain get ahead of you and say 'well, Tillman, YOU must not have that big a problem', cause I'm not saying that at all.
And unfortunately although I know a great deal about dealing with withdrawals, I'm not permitted to offer anything resembling medical advice here, so you'll have to go elsewhere to look up 'detox recipes' or whatnot ... given that you've stated that you're refusing to see a doctor ... which is where I've gotten my detox meds in the past.
So ... good luck with that part, and keep coming back!
