My son started Vyvanse yesterday - took 1/2 of a 20 mg capsule (dissolved in H20) with toast. He noticed the ability to concentrate and focus. He even read 3 chapters of a book - willingly! However, today I gave him the other 1/2 dose - woke him early so it would "kick in" by school. He threw up (mostly dry heave) about 30 minutes later. We will try tomorrow with food. Very anxious about potential side affects. Don't want to have to keep uping the dose down the road to maintain effectiveness - don't want risk of addiction and/or withdrawal issues that are so severe he can't go off. CAN you go off of this for good at some point?
Yes, one will build a tolerance to Vyvanse over time. However, I've been on the same dosage for over a year. Tolerance doesn't typically build so quick. I would venture to say that your son got sick because his body may not accept an amphetamine early in the morning, especially without food. Personally, it works much better for me with food. Side affects are generally set in the first time Vyvanse is taken, and usually aren't severe (i.e. jittery, sleeplessness, rapid heartbeat, etc.) There is a risk of addiction, so the medicine should be monitored. However, you CAN go off of Vyvanse for good at any point (consulting your doctor first, of course.) Hope this is helpful!
