My doctor prescribed me Adderall 5mg 2 times a day and this was not working for me. I was on this dosage for a little over 2 weeks, then my dosage was increased to 10mg 2 times a day. I am still not seeing how this is doing anything for me. I fall asleep on this, i feel like my body is crashing. I feel irritable, my thoughts still race and cant seem to get on track. Its like it doesn't last long. I am now waiting to start Vyvanse 30mg 1 time a day. Will i notice a difference or will i just be wasting my time? Please help.
