"i was on vyvanse 50 mg for bulimia, it stopped the binge eating however i could never fall asleep not even with a sleeping pill and i always felt so very depressed in the late afternoon, my doctor told me about mydayis , i switched to mydayis 25mg which works even better!!!  i get a good nights sleep without a sleeping pill. the only side effect is dry mouth and an occasional headache if i wait too late to take it. its always best to take it early in the morning, i take mine at 6 am, i still have remained free from any binge eating episodes. thankful for this medication!"
