That was my hunch (See my post #800)
But do you add sugar to everything you eat and drink?
No, rarely use it and don't drink pop. But I always have one beer a day.
Beer was the first thing to go from my diet. When I gave up my habit of having a pint or two with a cheeseburger five days a week for lunch my gout disappeared and has not come back since. I drank bourbon instead, limited to two a day, for a while but eventually gave up all alcohol. That led to further improvement.
Realizing it was the food that was causing my problems I started educating myself and experimenting with dietary changes.
I suffer from psoriatic arthritis (Among other things). As I aged it got progressively worse until I got educated and started adjusting my diet. At 65 I could barely walk with a cane. I never got a solid night sleep due to the pain. The skin rash eruptions were disgusting, painful and unsightly.
Now, at age 74. It's all gone. I can walk as far as I want to; even run a little! I sleep like a baby. The only "Drug" is take is a few drops of CBD tincture before bed. a few years ago I was basically just waiting to die and hoping it wouldn't be too painful. Now I wake up looking forward to the day and excited to be alive.
So it's working for me. YMMV
