Hi Fiona, I suffered with horrendous heartburn before I started LL, the first few days into it I had none, then I made the crisps from the unofficial reciepe guide, and yes the heartburn started up again!
Will be giving them a miss from now on.
I had been getting it before cd for quite a few months actually, having never had it before in my life. I have been to the doctor a couple of times and he's now perscribed me something to surpress the acid in my stomach. I have to try it for a month, so hopefully that does the trick!!
I can't imagine why the crisps would give you heartburn strange! Our bodies are funny things!!
