My experience is anecdotal but I drink both. I've found that once you're a heavy caffeine drinker that you hardly notice it's effects on things like sleep. Alcohol is different. 8 drinks before bed and I wake up tired, despite my usual bedtime. I drink way more caffeine than I do alcohol, yet alcohol is the only substance that has ever seemed disruptive.

Yes, after a while your body gets addicted to caffeine and adjusts to the amount you are ingesting, so you need to increase how much you're taking in order to keep feeling the high you expect from coffee. If you suddenly stopped assuming caffeine, you'll start suffering from withdrawal symptoms such as headaches and drowsiness; this is because your brain adenosine receptors are accustomed to a certain amount of caffeine (which is itself an adenosine antagonist). Your brain receptors recalibrate themselves after a while if you stop drinking coffee/tea, or if reduce your intake of caffeine to a smaller amount.

  Not sure why you're getting downvoted. The withdrawal symptoms for caffeine are brutal in my experience. It's really surprising every time I dabble with having an espresso a few times a week when I'm in a cafe-frequenting mode. Even just one week of having a double espresso every other day will leave me with 1-2 days of terrible headaches and nausea beginning 1-2 days after completely stopping. No other drug I've experienced so quickly establishes such miserable withdrawal conditions. And I've been around the block in this neighborhood.

8 drinks is quite a lot. That much alcohol affects a lot of things.

I think with 8 drinks I would either die or have a weeklong hangover :)

  8 drinks are about 6 beers of 375mL volume here. In my country (Australia) beers are typically sold single, by 6 or by 24. So having 6 beers isn't uncommon. It's something you may do at a weekend BBQ during summer.
