Most of us just carbonated it like beer. I tried both ways and mt favorite was with a little Splenda and highly carbed.
Here is a link to carb amounts:
And here is one per bottle size if it helps:
BOTTLE SIZE / SUGAR AMOUNT
12 ounce bottles use 3/4 tsp.
16 ounce bottles use 1 tsp.
20 ounce bottles use 1 1/4 tsp.
22 ounce bottles use 1 1/2 tsp.
1 liter/quart bottle use 2 1/2 tsp. (Included with Premium Edition)
2 liter bottles use 1 1/2 tbsp.
3 liter bottles use 2 1/4 tbsp
You can convert if you need bigger sizes...have fun!!!
