Depakene and Diabetes Medications

So long story short , I am epileptic obviously .

Been on Depakine for almost 16 years now , and I gained massive weight.

My sweet tooth , appetite , and even when I start working out , my metabolism is incredibly weak , although I lost a lot of weight before 2 times.

So I have 2 questions : anyone here using Glucophage or any metformin diabetes 2 meds to control their blood glucose level ( I'm prediabetes myself) along Depakene.

2nd question: I am really fed up with depakene side effects : between hairloss, weight gain, shivering , etc.

What other meds has less effects.than valporic acid , and does anyone recommend cannabis oil and keto diet for adults.

And wish you all recovery
