First night w a buckwheat pillow..I have questions

I received my buckwheat pillow yesterday filled very full with buckwheat. I was nervous to take any out, wasn’t sure how much so I slept on it last night completely full. It was hard to form a dent in the middle for my head so I guess I should have known. I woke up with a terrible stiff neck and pain. (Actually not as bad as the microbead pillow my mom had bought me though–OUCH).

I’m going to put some heat on my neck and get my hubby to help remove some of the buckwheat. I know this varies from person to person, but how much is at least a good start to remove? It barely gave at all last night.

Gentle hugs my friends
