yes, your body seems to be telling you something. listen to it.
For the last 12 years, i have taken Prilosec or some variation of that drug to control the unending heartburn i have every day. i've been eating primally for about a week now, and haven't used a single pill without any issue. yesterday, i had about 1/3 of a slice of gooey butter cake and had the worst heartburn i have experienced since starting the primal eating plan.
trust me, i won't be indulging in too many more sweets after that episode.
