Hi Karen,
Good luck with experiment. Pete (Dakotadan) was NSD for a year, then went back to starchy foods and has been able to follow normal diet since. Me... I am not so lucky. If I cheat, can typically feel some stiffness the same day, if I continue then I slowly get worse from there.
To get back out of flare I go very strict and usually take a few Tylenol's. However I do not cheat to the point it brings about a big flare.
Hopefully all works out for you and can add some starch back in.
In regards to taste changing... my taste buds did. Does not mean I do not enjoy the taste of starchy foods, I just got to the point I did not crave them like I did early in the diet when I eliminated if that makes sense.
