7 minute timing on nasal meds, is really working,(= movement no pain) Had visit from @paulgrounded with nice Earl Grey tea! Managed to stay awake mostly. Did snooze later in spite of plans to stay awake and get back to normal sleep pattern. Ate jelly and ice cream! Very happy no pain episodes so far today(*hopefully*)
So if I squirt the alfentenil up my nose and wait 7 minutes I can move without screaming. Dose lasts for 15 minutes. 2 squirts and I managed to have hot bath and hair wash and dressings changed with no pain, tho I did get a bit of the hissing ears and giddiness.
