Starting to wonder if I have an addiction

[Powder]

Seriously, I'm trying to decipher if poker is just my new hobby or if its taking over my life. I'm still a beginner, I've only been playing at live tables for about 2 months. As of late, I play at the casinos here in town about 4-5 times a week, and usually for several hours at a time. Then sometimes when I get home, I play on the internet. Then I think about it throughout the day when I'm at work, how I should have played this hand differently, or whatever. I even have dreams about playing, but this isn't as far out of the ordinary as it sounds, as I have crazy dreams all the time about my everyday life. I'm not losing, so this isn't a situation where I just keep blowing money and can't stop. I'd say that ever since I started playing, I'm up a little, but not much. I started out playing $4-8, and was up and down with it. I got frustrated with it because people were calling and playing with everything, horrible cards. About a week or so ago I started playing no limit. It seems to be working out better for me. My last few outings on the no limit tables have been +$200, -$150, +$250, +$850, and then today I took my worst loss yet at about -$300. I think my game is getting better the more I try to learn about it. I'm currently reading the NL Theory and Practice book, which only through this first few chapters has taught me a lot. I beleive poker can be a supplemental income for me, but I have make sure I can keep my hands around it. Is this normal?
