I want to know the answer to the following question:
How did Nasser deal with the stress of the UAR's collapse and Amer's intransigence?
All the background I'm provided with is that "According to Boghdadi, the stress caused by the UAR's collapse and Amer's increasing autonomy forced Nasser, who already had diabetes, to practically live on painkillers from then on.". Is that enough to answer the question?
Answer: yes
