With stimulants, you don't really need to taper down the amount of drug you take because they have short half lives and don't remain in your system for long. They're not like SSRIs. So, no worries. But, thanks for your concern! I'm doing OK except for the sleep problem. I'm trying different things (like the holiday from Vyvanse) to see if I can solve this problem. I did go see my GP about the sleep problem last week but he was no help, so it's up to me.
