"i started this medication a month ago. the first few days the side effects were pretty bad so i stayed in bed. it was mostly nausea, dizziness, extreme fatigue &amp; then insomnia...after a few days almost all of those subsided except for the fatigue and insomnia. now its been about a month and i mostly just suffer from some brain fog and some fatigue, not nearly as bad,  but my appetite is basically gone. i really dont even enjoy food that much anymore &amp; sometimes skip a meal or have to force myself to eat where as before i couldn&#039;t stop eating, i have a horrible food addiction.so this has really helped. i lost about 20 lbs my first month. very happy with this medication and i feel it has saved my life as i am pre diabetic"
