Can lowering sugar be the cause of too much medication?

You have given us too little information. We do not know anything about the medicines used, how your treatment goes, what diagnosis (what you suffer from) has been made, what drugs you use in what doses and what treatment regimen. There are a lot of questions. If you are under the constant supervision of a diabetologist, please visit him. He knows your condition and will certainly help. You can also go to your family doctor. Sugar drop - hypoglycemia is a health emergency. This cannot be underestimated. I encourage you to go to a specialist.
