Please answer a question about the following article about Gamal Abdel Nasser:

In early 1962 Nasser again attempted to wrest control of the military command from Amer. Amer responded by directly confronting Nasser for the first time and secretly rallying his loyalist officers. Nasser ultimately backed down, wary of a possible violent confrontation between the military and his civilian government. 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.

How did Nasser deal with the stress of the UAR's collapse and Amer's intransigence?
