Yeah, 9 to 10 a day is a health problem. Not like alcohol poisoning or anything that will show up right away, but more like liver damage and stuff that slowly accumulates for years. Yes, you can go for years and years at that rate with no signs of health problems, and then suddenly your liver gives out and you have a big problem all at once. Warbler is right–there is some urgency, even if it’s not apparent at all right now. By the time it finally shows up it will be very hard to deal with.
