Method Question concerning 2 methods

[RecycledAtoms]

First: I have been told that taking sildenafil (viagra) and nitrates (such as nitroglycerin) within 24 hours of each other can cause blood pressure to drop to irreversible levels and almost guarantee death. Firstly, IS this actually true? Secondly HOW effective is it? Thirdly, WHAT are the side effects?

Second: how about benadryl (diphenhydramine) and unisom (doxylamine)? I have heard that if taken in enough quantities this can be lethal. IS this true? If so, HOW much of each would be needed? What are the side effects?
