"i started to take victoza 0.6 mg for weight loss, three weeks ago. after jumping through several hoops with insurance to cover the med, i was hopeful and excited to start this med and get results. first day was awful; headache, fatigue as i have never experienced in my life (shoulders/back/neck), nausea (like at sea), dizziness, blurred vision, constipation, gi issues i&#039;ve never experienced before, dry mouth/dehydration, nightmares (when able to sleep) night sweats and insomnia. i tried to stick it out (2 horrible wks) in the hopes the side effects would subside; they got worse. i ended up passing out; hot/cold clammy sweats as if hypoglycemic, yet was not (140). i was taken by ambulance to the ed where i was given 2l fluids... beware!"
