I reduced my caffeine intake and it was a good thing for me.
I used to have an instant cup in the morning and I would put like 2 or 3 spoons in.
And then during the day I would have soda that had caffeine.
I cut back to just one spoon of instant and cut out the soda with caffeine.
So much better. I go to sleep now at night. I no longer really notice restless legs.
I am working toward getting rid of my morning coffee as well.
