Hello,
You are experiencing sweet smelling sweat and breath, You are suggested to get clinically examined by a GP at the earliest. Sweet fruity smell of the sweat may be indicative of 
ketoacidosis. You will have to go through  few required tests like blood pressure, amylase, blood acidity, ketone level, blood sugar level, 
arterial blood gas, blood 
glucose or potassium, etc.
Your treating doctor may ask you to do 
Urinalysis (R/E and C/S), chest X-ray, blood electrolyte tests, etc., done to confirm diagnosis. You will be accordingly treated with fluids, electrolyte replacement therapy, 
insulin therapy9if required), etc. Stay away from addictions if any.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
