I would wait until you finish your first cycle before you start planning your next. If you train hard, rest properly and eat like a lion and not a rabbit you will make incredible gains. If you can keep as much of those gains as possible you can start another more or less identical cycle from a better place than the first. You'll probably realise you don't need to keep upping the ante every time. And if you don't keep your gains my guess is you won't keep dbol or any other gains either.
