Yes, thank you. My husband went through the same problems as that gentleman I just read about back in October of 2013. Went to emergency though, and a CAT Scan was performed. Nothing showed up, all clear. Everything else checked out, EKG, BP was a little elevated, and had lost sight during that day, with vertigo problems and vomiting. He also takes Vyvanse, has a pacemaker, high cholesterol, high BP, etc. He too, probably had a TIA we were told later by a Neurologist he was sent to. When I asked if Vyvanse could cause this, the Dr. said to check with the Dr. who prescribed the Vyvanse. This is peculiar., I think. MY email address is: YYYY@YYYY Thank you!
