Lots of great recommendations already, so I'm mostly here to reinforce the "Don't give up!" theme. 
So, by all means, look for some not-so-sweet flavors you enjoy. But keep in mind that your tastes are still changing. You don't yet know what you might like two or three weeks from now.

The first two weeks I was vaping, I felt the exact same way about sweet juices: I liked some of them, but it was just too much. I needed some less sweet flavors. That's OK, and there are lots of them available. But I would also add this: After the first couple of weeks, my tastes changed a lot. I mean A LOT. Suddenly the fruit flavors were not overpoweringly sweet, they were just delightful.I really like all the sweet flavors but you can only take so much of that b4 it starts to give you a nauseated feeling.

If you like that flavor, get a sample pack from Johnson Creek. You said you tried their Domestic but want more throat hit. Try some small bottles of their other flavors.I started this adventure with the blu e-cigs and the flavors in those were awesome so that held me for a few days but the nicotene cravings weren't being satisfied so I knew I had to go with something a little stronger or I'd definitely give up.
