No, I don't think you're out of the woods yet, not by any stretch. 200 days is certainly a pattern-breaking streak, and you can continue that to 2,000 days if you wish, but it isn't guaranteed.
For 6.5 years my conviction for sobriety was rock-solid, temptations minimal/nonexistent. Lately, it's been tougher, just because life has gotten tougher. I'm almost 7 years in and don't feel I'm out of the woods, really. Everyone's different.
I've seen people fall when they let pure inertia carry them, the kind of thinking that goes: "Well, I've made it 200 days, I don't want to mess up this streak so I won't drink tonight." Eventually, in some circumstances you can't anticipate, perhaps in 1 year or 3 years or 20 years, that reason -- the inertia -- might not be enough to keep you from drinking.
