I've used the refrigerated ones in the past, and I, too, would forget 90% of the time. I forget the name if the one I use now, but it's an affordable one from Costco. A cheapie generic one I bought at Walgreens, a few years ago, gave me horrid gas pains and bloating. I also make kimchi, because I love it, but also for the probiotics. Although now that I think about it, when you make yogurt, you have to add cultures to it. I know my kimchi ferments, the jars pop when I open them and it has a carbonated feel in my mouth, but I dunno if I'm actually getting good bugs in there?
