I’ve had a headache off and on for the past three weeks. I’ve had enough Tylenol to kill a horse. It’s been down to 1 out of 10 since yesterday. It’s ramped up to about a 6 some days. It really would be nice to get rid of this. Causes? Stress, the accident with the Soul (whiplash), caffeine withdrawal, something I ate or drank … hard to say.
