How Can I Manage Body Tremors, Sweating And Vomiting After Taking 2 Caffeine Pills, 2 Excedrin And A Vyvanse In A Short Duration?

I took two 200mg caffeine tablets, two Excedrin migraines, and 60mg Vyvanse in a short period of time. I feel really really bad. I took 25ng hydroxizine to try to slow down. Idk what to do. I puked, i feel shaky and sweaty and like I could keep puking. Help?
