I understand what you mean about not wanting to do the fiber because you dont feel like you're eating enough, but honestly, I was eating once or twice a day just a little bit and once I started taking it, I went the next day! And I have been going somewhat everyday and my pain in the morning has reduced significantly! So maybe when you start taking the acaia which is 100% SF, I think, you could be able to tolerate the IF way easier. Just start out with a small dose. I took a 1/2 2x daily. I should also mention that I am not sure if I get even 1% of IF a day haha which i know isnt good, but like everyone else im scared to add it in! But really, the acaica is good for me even without the IF.
Also, could you post the link for where you found that lists of foods and how to put them together? Thanks!
