Hello, Vyvanse does range is 10\u00a0mg (smallest) to 70\u00a0mg (largest) so 20\u00a0mg that you are taking is not a very high dose. Vyvanse has a long list of potential side effects, but diabetes has not been described as one of them.  Serious side effects are heart related which is why heart testing is recommended prior to starting the medication. Common side effects is loss of appetite and weight loss, again these are not related to diabetes. Hope I have answered your query. Let me know if I can assist you further. Take care
