... until the next time...
Please tell us what's not nice about advising you not to drink until you black out? Every time it happens you talk about this fear. Besides, to drink that much is just plain unhealthy. Don't allow it to get to "a next time".
The bolded text is encouraging. It shows you know you're being irrational despite what your brain is telling you. Perhaps it's time to learn how to talk back? (therapy/meds).
