<s>[INST] Last night I was sick pretty much on the hour from midnight until morning. Had a slight bout of diarrhoea as well although nothing to actually pass. Also have painful kidneys / lower back which I think is probably dehydration ... Any advice other than drinking lots of fluid (currently trying that but brings the sickness on)? [/INST] Hello, Welcome to HCM, Along with water you can add electrolyte powder which will help in combating dehydration. For pain you can take anti spasmodic s like dicyclomaine. If the diarrhea doesn't subside you can consult your doctor. Regards </s>
