In my experience with sub, the thought of taking more would come on because I wasn't high, just normal, undopesick if you will. This is all about saving your family and business and in the end, your life. It's not about getting high. This is why you are here, on BL, trying to find a solution and not homeless alongside your junkie dealer "friend."
If you are feeling OK, that's a good thing, keep doing what you're doing in terms of sub dosage. Get stable again, and go from there. Wishing you the best. I'm on Day 5 of no sub, of course I want my DOC, but I'm not going there. Once you get stable on subs, kratom may be helpful in getting a little "relief", in the name of harm reduction.
