Which laxative tea do you use?

The last few times I've done the Master-Cleanse I used "Get Regular" from Yogi tea, but they updated the recipe and it doesn't seem to work as well as before. I also have used "Smooth Move" by traditonal medicinals and am having the same problem. So I switched to a brand my girlfriend brought from Mexico called Shaklee and it works great, the problem is I only have a few bags left. I'm just finishing up Day 4 and I'd like to hear what you recommend.

With the old "Get Regular" I'd HAVE to wake up around 5:30 to do my business, now nothing happens until well after the salt water flush.
