Rin, It's possible Frenilla *was* available in Near Zero and has sold out, I just am not sure. If that's not the case, since all the other flavors are available without nicotine intentionally added, I would imagine Frenilla soon will be. You could PM Kent Brooks and ask about that, he's great at immediately answering questions.
You asked about H1N1, and I personally LOVE it. It's technically a tobacco vape, and probably one of their strongest flavors, I know how picky your palate is! The website has tons of reviews describing the flavor much better than I ever could. Fresh it tastes like Snickers candy bars with plenty of almost a roasted peanut taste. As it steeps there is a change to more caramel, vanilla and maple with the tobacco coming more foreword. I taste cinnamon, but there is no cinnamon actually in it. Some people find it all "too much", but I smoked for 40 years and it's perfect for me because I need "in your face" flavor. It's in my daily rotation, every day. It's the one liquid I do NOT buy much ahead of time to let steep. I like the change, and it isn't one of their limited flavors, so it's always available. You can read more reviews and see what you think - if you don't like it you would have no problem selling it on the classies. Hope that helps, and as I said, it never hurts to ask Kent (Clark) about the 0 nic option.
