pill making me feel sick

so i'm on the pill and this is the third pill i've tried and i constantly feel sick, i can't eat certain foods but i want to give this one a proper go and see if it calms down - i've only been taking it for 2 weeks but i can't think of things to eat in the meantime which don't make me feel sick - does anyone have any suggestions of food i could try and hopefully bypass this sick feeling??
