In order to save on vyvanse pills, I've only been taking two in the morning. At 6:00PM I am ready for bed. I sleep for two hours, wake up for two and then it's back to sleep. Talk about not having a home life! I feel so guilty that I am not spenind time with my wife and son. I wish I could beat this fatigue. Yesterday, I had both a B-12 and testosterone shot. They don't seem to be working yet. I am hopeful though.
