Are there different dosages available?The stimulant crash is real, as is the appetite suppression. As my folks are starting their stimulant trials, I typically have them keep a food, water, and sleep diary to ensure that they are eating and sleeping enough to counteract those side effects. Vyvanse has arguably the gentlest onset and offset of the stimulus medications, but the effect can still be disruptive, especially in conjunction with increased productivity/fatigue during the day due to the direct effects of the medication.
