i was ok earlier in life now im 58 have reverse reactions

This is pissin me off !!I could take z quil, beta blockers, BP meds, coversyl, Ativan, zoplocone, not all antihistamines, Benadry, kava kava, and melatonin !

Now when I need to be put to sleep or my heart rate controlled does the complete opposite to me!!And you tell doctors or pharmacist and they say well that's strange!!

So, if I take day quil I will be sleepy?????I would take z quil and sleep like a baby,years ago!!
