@JacquiMorrison I actually find that the bolus works a lot more quickly in my arms than my legs - I only recently started using my arms, but it has worked wonders for getting a reasonably decent response after a meal, rather than continuing to climb for two or three hours first.
I also find
@GrantGam s method to be very good - wrapping your arm across the torso seems to create a bit too much tension and makes it painful. If you are nervous, try sitting down at a table or a desk, holding your arm out in front of you and gently relaxing it so the elbow comes to rest on the table, creating a kind of 'v' shape with your arm, and then go from there.
