even video gaming. It is good to get checked for under lying issues other wise you can just transfer your addiction to another addiction....
like when you end up 300 baked things and someone is like goodness are you doing a bake sale or something?
check underlying causes.
try something like knitting which ...is not as good as gaming, but uses some of the same movements, and also has a reward system buitl into itin the senseof a physical finished product.
I used to be addicted to Starcraft 2 and Worms Armageddon. I wasted a lot of life in those days. I read up on it and all of the research shows that obsessive screen time increases depression. After reading enough articles I began to hate screen time for entertainment purposes and now when I do play video games I feel guilty. I feel like I'm cheating myself and missing out on life.
I've established a list of things I find to be a valuable use of my time, like you with baking. Keep working on that list and maybe research all the negatives of your habit to help you build a hate towards it.
Video gaming is the enemy that is trying to defeat you, fight back and let hate towards it feel your veins.
Best of luck to you and overcoming this powerful addiction.
Best,
Brock
He says the same as you...it is his relaxation from work...I got him to listen as to how I feel about that much time being taken from time for us. He has started to make some adjustments...like you said putting feet up and trying to relax...his back usually hurts too after that....but he has a curved spine and siatica to boot...makes things interesting at times...to actually change may take baby steps...but you sound like you are in the right direction!
Hope all starts to feel better real soon!

The book I suggest is "The Power of Habit" by Charles Duhhigg.
