Has it changed my mood to more mellow ,this less caffeine mode ?
Yes, but lethargic, craving time is still right after lunch through to mid afternoon.
Today I spaced out the caffeine intake with less first thing in the morning and a bit more at lunch. Still absolutely none after that except decaf.
Next week I will reduce the caffeine further.
It will have to be gradual or I will be back to full strength before I get new habits.
