I am starting out at every other day dosing. It works wonderfully and I otherwise am so happy with it (especially the loss of appetite and wanting to "frenzy feed." I came through the pancreatic symptoms first week, but I can almost set the clock for neck pain, radiating into head on left side only and then severe sinus pressure. Pseudoefedrine does not help. Last about 10 hours. Debilitating - I can't work, I can't sleep. Have tried taking different times of day and still same result. This is my third week on Victoza. Thanks for any comments.
