2 days ago, I was sick.  Yesterday, I was sicker.  Today, I feel terrible and am much worse.   I can't get anything done.  That means something is building up in my system.  It is obviously a reaction.  The only thing I've eaten all three days is Lays Potato Chips.   Today, as I was bent over for a minute in pain, I remembered that I'd had a reaction before to something I seemed to be okay eating.
Each time I have a reaction, I write down the foods I had 24-48 hours prior. Looking back, I had written that I suspected the chips.  I think it's confirmed now.  It kind of sucks, because the only other chips I can eat are the Lays Organic Potato Chips.  They're not sold locally.   But I'd much rather go without food than feel like this.
