Jon- I believe regular sinement should be taken 30 mins before a meal, and preferably a meal with little protein. With CR it does not make any difference. You might try taking 1/2 dose more often; it may smooth out your symptons. I also take 1/2 25/100 with 1/2 cr 50/200 twice a day and 1/2 25/100 when I feel it is needed. Dick Swindler (52/15)
