"my experiences seems similar to ptmazeik&#039;s review.  days 1 and 2 were fine but day 3 - oh boy. i took my shot at 5pm and i have to admit, i was excited. i was prescribed victoza for weight loss. i imagined my extra weight just falling off. but the side effects were not worth it. on my 3rd night i was awoken by a butterfly &#039;wobble&#039; spreading up my chest, arms and head. i thought i was having a heart attack. it was an intense nauseating feeling. it lasted for 13 hours. i couldn&#039;t sleep, i was frightened and i didn&#039;t know what to do. i eventually found milk would ease my symptoms and that excessive acid was a part of what was happening. 27 hrs had passed from my shot and i felt fine. utter relief. wont take it again. i did lose 3lbs ;)"
