"i was prescribed vyvanse chewable 30 mg in the am and 30 at noon. i loved it, but had a month where i didn&#039;t take it regularly at noon. dr suggested this because of the extended release. 2 weeks in: my sleep is concerning. i haven&#039;t hit rem in 3 days now. i have no appetite even in the am before i take the mydayis. i have to force feed myself, even icecream is a struggle after the 3rd bite. the 2-3 hours after i take it i feel lost, can&#039;t track conversations,  no/minimal recall, i can&#039;t even prioritize. after those hours things level out a bit, but i don&#039;t have the motivation i had with vyvanse. 
i believe there is link between loss of quality sleep and stuggling to meet my dietary requirements and how the drug affects me."
