Diet Coke
Not that it should come as any surprise to you guys, but I am addicted to caffeine. Administered in the form of Precious Dr Pepper.
Intervention on A&E, the first and last cocktails of the day, FaceBook and the internet in general, underachievement.
Heh. Being addicted to the show is far better than the stuff they show people addicted to. Did you see that chick that huffed “refrigerated air”? I didn’t know you could get addicted to doing nor that people even huffed things anymore. What a crazy episode that was.
I was stuck in a Marriott Hotel in Hong Kong without a book - I read the entire Marriott Way. :o
Caffeine. It doesn’t matter if it’s cold (diet soda, or Rockstar types) or hot (coffee, black tea etc), as long as there is plenty of caffeine.
Breathing. Can’t give it up. 
Sugar. I have serious cravings when I try to give it up. And the Dope of course!
Chewing gum. I pop piece after piece like a madwoman.
Oh, those are awesome too! I’m telling you, whoever came up with that idea knew it would be manna from heaven. 
And I just now remembered I’m addicted to wearing a certain pair of sweats, tops and bottoms. They’re way old and have paint stains on them, but they are so comfortable that they get a pass in the looks department.
Afrin
Coffee
Fiber supplements
I’m actually off of afrin and coffee (recently), although I do drink decaf. As to the metamucil, I don’t think I’m physically addicted, but if I go off it for a few days then my…ahem…habits are less regular. Then again, I’m dieting, so that might explain things too.
I’m addicted to dihydrogen monoxide.
Are you crazy?! that stuff can kill you!
Having a job. I’ve had set tasks that I’ve been paid for since I was like 8 and outside the family from not too long after that. Being without work, for me, is like someone coming off heroin.
My morning coffee from Tim Horton’s (XL regular, pleaseandthankyou).
Like Markxxx, it’s not so much an addiction to caffeine per se, it’s all about the coffee… the rest of the day feels a little off if I don’t start it off with my big honkin’ cup of coffee.
I’m also totally addicted to Extreme Chef Wars on my iPhone right now. It’s a completely pointless and silly game, but that doesn’t change the fact that I’m hellbent on total world domination.
Smokes (Yeah, I’m on the quitting thing, I’ve heard it’s bad for you)
Diet Coke
My morning Tim Horton’s coffee (Large double double, you take the pain away)
Disney World (I must, must always be planning a trip there or be there)
Internet for sure.Play me off Keyboard Cat!
Books. Not just reading them, but buying them. It’s hard to walk past a book store and not go in. If I am in a bookstore I feel very real feelings of failure if I don’t find a book or twelve and buy them. I don’t read nearly as much as I used to (toddler and household stuff and, yes, the internet take up what used to be reading time) but I still love buying them. My “to be read” stack is HUGE.
I’ve gotten better, though. I’m in a rental while we sell our old house and hunt for a new one, so I’m not buying anything. Once we’re in a bigger place. . . well, I have a lot of months to make up for.
I hear you on this. My wife asks me to just go to the library instead of buying new books (or putting them on my amazon wishlist).
I should…but…
Turning on the computer as soon as I get home. I realized one day about half a year ago that I seriously was experiencing some kind of dopamine reward (giddy feeling in the stomach) as I was walking into my room to get on the internet. Insane.
Whoops. Put me down for nose spray too.
