I was taking Adderall multiple times a day, and then was recently switched to 50mg Vyvanse. I take it in the morning on an empty stomach and it still takes about two hours to start working. I dont want to have to wake up 2 hours before I have to do something like go to work or school. tested it one morning, I woke up about 630am, and I took a 50mg Vyvanse along with a 10mg adderall with a full glass of water, withing 20 to 30 minutes I was ready for anything and then the vyvanse kicked in so i was good to go all day.
