Getting My Toes Wet

I think the time has come for me jump on the Torani Sugar Free Syrup wagon and start spicing things up a bit in my post RNY world.  I am quickly growing tired of plain old vanilla and orange protein shakes and it's only been about a week...this is not looking good for the future LOL

I looked at my local grocery store and they only had one SF syrup and it was Hazelnut...no thank you.  So, I called over to the next city and they have SF caramel and SF chocolate.  I think I might pick up the caramel one and then possibly order some others online.  Anyone have any suggestions?  I'm thinking I want a pumpkin spice type flavor and a peppermint type flavor as well.  One thing I'm really going to miss is the Peppermint Mocha creamer this winter and am hoping to re-create that in a protein shake, which could interesting.  

I have heard though, once you buy one, you don't stop there and that your collection keeps growing and growing and growing.  Is this true?  And if so, am I going to have to add onto my house or would it just be a better bet to start looking for a new house now?
