ADHD and no meds

My husband was diagnosed about 2 years ago with ADHD. In the beginning, he read a lot of books on the subject and we talked a lot about it. He was prescribed Straterra, which has to slowly build up in your system. I felt like it was working and we had a lot fewer angry outbursts. BUT, it is really hard to tell when/if it worked b/c he often forgot to take it. Since it had to build up, it was almost like starting all over again each time he missed a few days. He said he felt like it was helping, but a few weeks ago told me he is going to stop taking it b/c he feels like it is causing him anxiety. Since then, I have noticed more of the addictive behavior (ie... he stayed up almost all night playing computer games, evidence of internet porn viewing, etc.) and he has started chewing tobacco again, which I feel is a form of self-medication.

He is starting his own accounting business, (he is a CPA, but left a firm after 5 years and was let go of another after a year and a half) so I worry about how he will handle everything without meds. He has no medical insurance, so he avoids the doctor. Plus, I have mentioned a few times about going back to try a stimulant med, but have not gotten much of a response and want to avoid being a nag. I am trying very, very hard not to treat him like another one of my kids, but when he gets things out of the van and leaves the back wide open, or burns an egg b/c he got up to work on his computer while it was cooking, it's hard not to. I work in the afternoons/evenings and am constantly worried if the kids are getting to bed on time so they have enough sleep for school. He seems to think bedtimes are optional. I also do not schedule anything the one day a week my son has to be picked up from school b/c I just don't trust that he will consistently remember to do it.

So, I realize that meds do not solve everything, but I would at least like him to try something different. How can I approach this without sounding like a naggy mom? Also, are there any ADHDers out there who are successfully functioning without meds?  Things are okay right now, but I am just always worried about when the other shoe will drop.
