I never liked it until I got out of college and stopped drinking beer at degenerate levels. I found myself craving carbonation in my drinks regularly and I rarely drink soda, so I started trying seltzer. Initially I didn't like the odd taste you get from it and found that most flavored stuff clashed hard with the carbonation. Eventually I found that citrus flavors helped mask the odd taste until I got used to it. After a while I had trouble justifying paying for my water so I got a pony keg, CO2 bottle, and fittings from a buddy who was getting out of homebrewing. It isn't cheap to do if you're buying new, but worth it if you drink a lot of seltzer. I use a little fruit juice concentrate to flavor the glass/bottle/whatever I'm drinking from. I used to flavor the keg, but it was a lot of only one flavor to drink at a time.
