I couldn't handle it. Got some in Thailand cos it was cheaper (was living in Hong Kong). Took it for about 6 weeks, bled the whole freaking time, heightened sense of smell, lots of cramping, felt nauseous a lot. Hmm, this probably isn't a very helpful post! Best advice would be to get a 1 or 2 packets off your Dr first, just to try it out, they usually have samples lying around.
