I have been taking WB 150mg/daily for 3wks now and having strange side effects: headaches on right side of head returning, insomnia but once asleep I fall into a very deep sleep, neck pain, hungry one minute and not the next, decrease in intensity of menses, dizziness at times. Anyone out there with similar problems and if so what was done to calm them? I need to be on an anti-depressant but not wanting to take anything that causes weight gain or decrease in sex drive.
