I had a 15 pen stockpile at one point, due to all of those concerns we had! I have undisclosed Bowel Disease too (MJ is helping me with this), so have the extra worry of being cut off if the pharmacy found out.
I did take a break in orders when there were shortages and reduced it to 10, then resumed ordering one every 5 or 6 weeks to keep in with my pharmacy.
It felt quite reckless at the time, especially during the time we were only getting short-dated pens, but I'm so grateful I have those 10 to ride me through the next year or even up to the latest expiry of Feb 27.
I'm at BMI 20.5 from 38, so navigating what Maintenance will look like for me.
I'm sorry for those who are facing the price rises and can't see a way to continue, it must feel devastating. Hopefully the increase won't be as high as we fear.
