I had fairly little ones too, about the size of small peppercorns.

My triggers were pretty much everything. I could not eat more than 15gms of fat per day, so I had to really, really watch what I ate. I was so, so sick. I stopped breastfeeding because I was not getting enough calories for me & my daughter. I lived like that for 6 months and it was pure hell. Stress would also trigger an attack for me in the end, so I had to try to keep as calm as possible. One night I went to hospital after eating steamed vegies and steamed fish! It was just the stress that triggered me off.
Good luck hun. I hope you don't have too many attacks. Definitely try to stay away from as much high fat foods as possible and stick to low fat everything, the lower the fat the better.
