I would keep eating all list one foods in your diet unless you notice an increase in pain/frequency an hour after meals. I ate a lot of spelt items at first.  Lundberg makes a great brown rice pasta.  I would advise reading the posts on food.  You will get so many new ideas.    My IC is also severe with pain being my worst symptom.   The pain has been a huge motivator for me to stay on the diet and get better.  Some people see a reduction in symptoms right away while others take longer.  Make sure you join in the monthly support groups.  By understanding the cause of IC, it is easier to follow Matia's treatment guidelines because it is only a matter of time until your symptoms decrease.  When your herbs arrive make sure to take them apart from meals and track your symptoms in a journal.        I saw several breakfast ideas a while back.  One person made breakfast sasauge.  Baked potatoes are nice in the morning.  In Asia, they eat soup for breakfast.  I have made spelt pancakes and zuchini muffins.  Some people just eat a regular meal at breakfast. I would do several searches on this site using words like breakfast, lunch, dinner, ...  You can do it!

Yellow squash can be a problem for some on list 1. Have you tried broccoli? Have you tried spelt bread? What about your water? Tammy
