Sexy Transformers star Megan Fox has such a sweet tooth she has to guzzle vinegar to regularly cleanse her system.

The actress, 22, swears by the quick-fix method because it flushes out everything that's bad for her body and helps her to stay in shape.

She explains, "It's just water and raw apple cider vinegar, and it just cleans out your system entirely. It will get rid of, for women who retain water weight, from your menstrual cycle and all that, it gets rid of it really fast (sic). I'm not one for dieting or exercising, 'cause I'm lazy and I have a really big sweet tooth, so I have to do cleanses every once in a while 'cause of the amount of sugar I take in."

And the health-conscious actress even has a method for de-stressing after hectic days on film sets.

She adds, "I take melatonin to sleep. But I also have lavender oil all over the house, and if you put that under your nose, on your forehead, and I put it over my heart - it's just really relaxing. Something about that scent helps you to focus."
