My doctor switched me to Vyvanse (Lisdexamfetamine), which is basically a time release version (for ADHD and Depression). I benefitted from Aderall (Dextroamphetamine) but the UPS and DOWNS were too much for me. I now take 40mg Vyvanse mid morning and it works most of the day with little or no crash. Unfortunately, Vyvanse is fairly new so many insurance cos. won't cover it, although there is a coupon online that'll help.
