"i tried victoza 0.6 a few months ago, had severe dizziness 24/7; stopped. wanted to try it again, as i have to lose weight and am insulin resistant. this time started at 0.3 (5 clicks). had the headaches (head, neck), burping + some nausea, but stuck w it for 3+ weeks before moving up to 0.6. after 2+ wks of 0.6, i&#039;m now at 0.9, largely w/o side effects except constipation. my endocrinologist says the best weight loss is at 3.0, but at 0.9, i&#039;m absolutely seeing wt loss (6 lbs in a month) and noticing distinct lack of hunger. i&#039;m cautiously giving it a rating of 8, because it still beats amphetamine-like appetite suppressants. if you have trouble, start very low and take your time moving up; so far, i believe it&#039;s worth it."
