This explains my crazy dreams:

Uncommon (affect between 1 in 100 and 1 in 1000 people)

Mood swings, depressed mood, personality changes.
Abnormal dreams, hallucinations.
Agitation, restlessness.
Changes in sensation such as burning sensations or numbness (hypoaesthesia).
Visual disturbances such as difficulty seeing fine detail, decreased peripheral vision.
Increased heart rate.
Hot flushes, sweating.
Dry nose or eyes.
Shortness of breath.
Abdominal swelling, acid reflux, increased salivation.
Rash.
Pain, stiffness or twtiching in the muscles.

I have also been "unusually" sad lately, I am generally happy and upbeat - that was another of the side effects...

Now I am re-thinking this drug but it is helping so much with the pain !
