i would have dizziness headaches and an over all feeling of being un-well?
the symptoms seems to be probably due to side effect of excess dose of iron. you should take it only after a proper investigation of your haemoglobin percentage and serum ferritin levels. so it is advisable to consult a physician and get a thorough evaluation done. for acid reflux you can take antacids and omeprazole and simethicone for gas formation. do moderate workout and take small frequent meals. hope this helps.
