"i have had adhd since i was diagnosed in 2003  over 15 years of trying every medication for adhd i have found a fit for myself and talked to many others that have tried different treatments i used to take 35xr with 10mg boosters now i take 3 10mg ir a day one when i wake up one at lunch and one before or around 4-5 pm the xr actually caused me to be irritable and didn&#039;t cause much change in my normal non medicated habits, unlike vyvance would. this works great for adhd if you have a doctor or psychiatrist that is willing to figure out what dosage works for you. eat before you take each dose."
