Sounds like you may be self-medicating which could lead to problems if it hasn't already. It would be better if you could find a better coping method for your boredom. I suffer from boredom too and understand how drinking could help you feel better. But if you think it is a problem then it probably is.

Are you seeing a doctor or a therapist? If so, you might want to discuss it with them. They may be able to suggest some better coping skills.

I hope you find a better way as drinking can cause many problems when it gets out of hand. But it sounds like you are a very self-aware person and that should help you through this though time.
