Reducing fatigue during pattern cutting?

Hello peeps. I have a tentative POTS diagnosis which is making my life hell when cutting large patterns.

I don't have a table big enough to accomodate cutting pieces while standing/sitting, (but if you have recommendations for tables please pass them on!) and crouching on the floor is losing me time because of how many breaks I have to frequently take to ensure I don't pass out upon standing again.

Anyone with similar circumstances, please give me your tips! Or just drop a comment for us all to commiserate on this annoying af condition if it also creates barriers for you during projects.

Cheers.
