You can go up to 5% sweetener if this is not sweet enough, as I found that is probably closer to what is in the original commercial version. You could also sub it for 2% Cap SS, or if that is too sweet for you, 1% Cap SS. You could also use up to 3.5% FW or JF sweetener. Or 0.75% of FLV Sweetness if you want to avoid the sucralose altogether.
