I was given 10mg diazepam in A&E once and I had a dramatic paradoxical reaction: I flew into a rage and had to be restrained :/
I was given morphine after an operation and that, as opposed to making me sleepy (as well as its painkilling effects), I was awake for three days straight and on a constant high. It was horrible.
I cannot tolerate injected adrenaline (like at the dentist when they put adrenaline in the anaesthetic to prevent te anaesthetic spreading systemically) as it, opposed to making my blood pressure higher, it makes me have a severe hypotensive episode. But I think this one is related to my antipsychotic usage.
