OK fellas - went for the test today.
Surprise No.1 - Appointment met on time
Surprise No. 2 - No exercise required.
Surprise No.3 - A seriously shite IV something-or-other that made me feel like I was signing off (sudden breathlessness/chest pains/dizziness/syncope)
which lasted for exactly 6 minutes, at the end of which the thallium was injected and the pictures taken. If they'd given me a choice between this and 20 mins on a treadmill the treadmill would have won hands down.
PS the reason for no caffeine is something to do with caffeine supressing the receptors that make the shite IV feel like you're checking out.
Apart from that a GREAT DAY!!!!!!
