This is one of the supposed benefits that users were sold on when bup programs were introduced; the trial results showed that some users could get down to 2nd day, or even 3-times a week dosing, rather than the need for daily 'done dosing.
It will be a purely individual case for you - many of my friends are fine double dosing (although, interestingly some chemists are trying to charge them per day, rather than per dose, which again was supposedly one of the whole advantages for bup, that it woiuld cost you heaps less over the week. If they try this shit, do not tolerate it and please contact you user org to let them know. it is against guidelines - methadone dosing is payment per day, bup is payment per dose); some still really need a single dose everyday. It is certainly unlikely that there will be any increased agonist effect however (ie unfortunately, you don't get more stoned) and OD is extremely unlikely (which you probable know by now as you've had your dose); or at least that's what the research, science, and everything i have heard anecdotally says.
BLers, please keep any info on bup coming in. Now that it is in full roll-out some interesting side-effects are appearing that weren't shown in the smaller clinical trials. User orgs can really make use of any reports of personal experiences that vary from what we were sold on. (One friend for example is having to use shitloads of speed to get any effect, same with alcohol. If others are having difficulty getting effects from non-opiates, that would be really interesting to hear.)
