Does anyone use a pen for 2 months

[ADHDdiagnosis]

Hello, I’m hoping to use my 3 pens for two months each minimum because they are high dose and I am now tapering down. They are so expensive I do not want to throw away but can anyone tell me if they have done this?
I know there is sometimes a lot of criticism when suggesting not following guidelines but I’ll take the chance and ask

Paid or free won’t make a difference. I didn’t say it constantly made things up, just that it is prone to it. Everything should be cross checked for accuracy, and given that the maths is so simple, you may as well just do the very simple maths yourself, or in an old fashioned spreadsheet.

Yes I was going to order more pens at the expected time. But now I’m thinking I may actually try to make this my last pens. Because I have 4. So a years worth if I can stretch it out. And I’ve used it for 10 months and reached my goal recently.

if I buy more in 3 months I worry about the expiry date. But I can see how I go

I had this. I had to start again at 2.5mg. And send in new photos with an explanation of why the long gap in ordering.

I'd urge caution. I haven't actually done this but am having trouble reordering from Oushk due to a long time delay. I managed to get a load of syringes ordered just before the price hike giving me a stockpile meaning I only just need to reorder now. They are now unhappy to represcribe at my current dose. It's a nightmare.
