I took 60mg of vyvanse about 12hrs ago and the effects have completely worn off at this point. I'm feeling pretty tired and groggy and wondering if it will be safe/effective to take 54mg of concerta to combat the exhaustion. I believe I read somewhere that concerta blocks dopaminne receptors so its not a good idea, but the vyvans have worn off now even if they are not completely eliminated from my system. Any help would be appreciated, thanks!
