Don't get too discouraged from all of this, DD, you didn't do too badly. Tips:

- Don't destroy existing constructions. Feel free to make your own if you want, but existing ones (Trade Depot and Still) were there for a reason! Build your own trout if you're not happy with what's there originally.
- Always keep an eye on your Dwarves. If you see a lot of blue arrows you know they're thirsty and can act quickly!
- Press Z regularly to view stocks. It'll show how much drink we have left.

I wouldn't be opposed to you having another turn!
