How the hell do I shower more

Soo I've just had one of the most embarrassing conversations of my life. My manager told me that people have mentioned I have an unpleasant body odour....

I know I'm active and should be showering multiple times a week, but I just can't get up and actually do it. If I have an afternoon free on the weekend I will, be otherwise chances are I will not shower at all in a week. I know that's bad and should shower like every other day, but I just don't know how to make myself do it.

Pursuing diagnosis right now, so no meds (yet). Do you guys have any tips?

Edit: wow this definitely got bigger than I thought it would. I will try all your tips 😁 I think partly why showering is hard is because many nights I get home late and don't want to wake/keep up my housemates, but I'm also definitely not a morning shower person. Here's to hoping I can make it a habit
