"i started takeing meridia in november of 2008. when i started i was 220 lbs. i now weigh 179lbs. i have arthritis in both knees and it&#039;s hard to exercise but with the extra weight off i find i can go for walks now. i have had one good side effect with meridia that is not on the list. i used to suffer from migraines. i was having at least 4 a month. since i started taking meridia my migraines have gone down to 1 every other month. told my doctor and she was shocked, and happy for me."
