HI,
THANKS FOR CHOOSING HCM,
you need not worry,the medicine is a good one
glyciphage i.e
metformin has a few side effects like
stomach upset ,
vomiting etc
but you may be normal in few days
change of medication may show variations in blood
glucose levels which vary widely making you hyperglycaemic and hypoglycaemic
so things you need to take care is about
1.medication needs to be taken same time of the day
2.food should be taken within the prescribed time and same time of the day
3.take food in smaller quantities at frequent intervals
4.plan a good set of exercises(not too sternous not too little)
5.fasting and more exercises may push you into hypoglycaemia
6.diet should be planned with your doctor or nutritionist
if the problems you mentioned above still persists even after you make changes according to my advice
meet your doctor and ask him to change medication
hope i answered your query
feel free to contact me for further queries
thank you
