@graylake Welcome to Mayo Clinic Connect. How concerning, to be going through all of this. It is almost 24 hours since you posted, how are you doing right now? Have you been able to stay hydrated? The headaches, light headedness and nausea could be from not drinking enough proper fluids for you, do you think?

When the medications were filled, were there any thoughts by the pharmacist as to when to take them, anything to watch for, etc?
