Can you take childrens Sudafed and Vyvanse?

I took 50mg of vyvanse and then 3 pills of sudafed (the ones with the actual pseudoephedrine in it). I was completely fine. I do not have ADHD or a cold, i was using both as stimulants/uppers/etc. It made me very hyper and jittery, but my friends were all hyper too so we just had a little hyper time.. haha. If you do have ADHD or a cold, then the effects will be different.
