Have had several side effects, nausea, lightheadedness, no appetite, lost 20 pounds, (not sorry about that), had all of these since beginning day. Just concerned about jump up of BS from 100's to 260's in one day. Would Tylenol cause this, I wonder? Taking it for headache yesterday. First time for headache, since beginning medication. Also considering taking Victoza at night, as the side effects are annoying. Thanks for letting me ask this question. Have not seen any reviews with this info.
