Definitely common if you start at a too high of a dosage. I talked with my doctor about it at my last exam. I told her I stopped taking it because of the diarrhea. I was resistant to taking it again, even though she was urging me to try it again.
Instead, she started me with 1-500 mg tablet in the evenings for 2 weeks, then adding 1-500 mg tablet in the morning. She said to try that for a few weeks and see if I can up the dosage on one end or the other to the full dosage (1000mg). I think that's the problem: starting at too high of a dosage. I've been on the 2 tablets a day for about a week now and no digestive issues so far!
Fatty foods are another huge culprit, so I find it easier to stick to my diet! :)
