I keep getting extremely tired about 6 hours after taking Vyvanse. The fatigue lasts for about 4 hours and my focus is even worse than in the morning, or just being tired alone. I think it's the effect of the drugs wearing off. After that, my body seems to rebound and wake up until late at night. The effect is similar drinking alcohol and then being more awake after it wears off, due to the body responding to too much serotonin. During the period the drug is wearing off, I'm extremely irritable, tired, and focus-less. Really considering switching to Adderall or Adderall XR generic. Kind of worried though because of all the negative feedback on the generic, although the generic is supposed to still be manufactured by Shire and identical. Who knows...
Anybody else get this with Vyvanse or Adderall / XR?
