I eat fish eggs regularly when I eat at Japanese restaurants. So what's the problem???

I didn't mention milk, because it's not a soft drink. If we're going to mention all kinds of drinks, then milk (cows' milk) is my choice for the very worst. It's awful stuff, no good for your health, tastes lousy, causes congestion, screws up your digestive system, just generally fucks you up bigtime, in my opinion. I don't drink it. I find it ludicrous and tragic that I live in a civilization which tries to get human adults to drink cow's milk every day of their lives.
