"today is only day three of taking contrave. the first two days i was so tired i could hardly stay awake at my desk. today i am taking a new approach and upping my caffeine intake by adding 1 cup in the afternoon in addition to my one cup in the morning. i read several posts here where others said they were very tired as well so i&#039;m going to stick with it. i&#039;ve no stomach upset or other side effects. i would love to go from 200 lbs to 130 lbs. i want to be able to walk the zoo with my grandkids, maybe even disney land some day."
