Well, congratulations on your commitment Dani!

I believe Reddi-wip contains sugar so it's not the best choice. It's also important to read the ingredients on the label as well as the carb count. It's not necessary to put sweetener into whipped cream either.

Remember too that there is a limit on cream you can use per day too.

Here are the instructions on stabilizing whipped cream.
Or, you can get a whipped cream bomb. I really like the one made by ISI .

For each cup of cream use 1/2 teaspoon plain gelatin and 1 tablespoon cold water.

Soften gelatin by sprinkling it over cold water and letting it sit for for 5 minutes.

Dissolve by placing it in a container over a small pot of simmering water. Or microwave in 5 second increments until melted.

Whip the cream until barely stiff.

Add melted gelatin all at once to cream during whipping.
Stop whipping when cream forms soft peaks.
