You're making a good choice.
Now, just a little hint, ok? Language matters. Don't say you're going to "try." Say you're going to "quit." Be assertive and positive in the idea that you CAN do this. Because you can.
And we're here to support your decision.
Oh, as for the money, well, I've already bought a new chaise lounge and took a trip to FL on my savings! Do put the money aside. You'll be surprised at how fast it adds up!
Shalom!
