How can I sleep on my back?

[25sheets]

I've just had my first microblading eyebrow experience and I have to sleep on my back for 10 nights. I'm a side sleeper so going to find this difficult. Does anyone have any tips?

I have had mine bladed 3 times (over 6 years, 2 top ups) I have never been advised to sleep on my back.

Having said that, because of getting pins and needles in my lower arm frequently I have decided I need to turn towards my back. I sleep with an extra pillow on either side, and lay with my back on that, so I am not laid on my arm (or my face) but not fully on my back.
