"i&#039;ve been on fluoxetine 10 mg for only 5 days. i have noticed some changes already. i have the worst anxiety and for the past 3 days, stressful situations seem a tad bit less stressful for me. i already lost 4-5 pounds on it. it makes me never think about food anymore. it makes me not hungry for hours. even a small granola bar can keep me satisfied and full for 5-6 hours... but i force myself to have breakfast lunch and dinner. things seem more brighter, colors are more vivid to me. overall i think it&#039;s starting to work. i will re-respond in a few weeks to touch base."
