"i was on the generic form of prozac 20mg for anxiety/headaches for about 6 months. during the first few months i worked out at least 3 times a week &amp; didn&#039;t notice a difference in my weight loss i became frustrated with it. i also felt like i needed more help, well once my dr increased my dose i maybe worked out once a week &amp; the weight piled on. i was always sleeping and didn&#039;t feel like doing anything. i went and saw my dr &amp; told her to take me off this bc it wasn&#039;t working and the weight gain was awful 20 pounds in 2-3 months. i started budeprion xl 150 mg once a day. today is my third day and i already feel that im not as hungry, i have way more energy, last night i felt like i was drifting in &amp; out sleep, may need meds to help sleep"
