Depression
"The extreme sleepiness and lack of efficacy ceased like a light switch - suddenly, after a couple of weeks of sleepy torture that didn&#039;t help at all, it WORKED for my depression and the sleepiness was GONE. I woke up one morning to find I could breath without the feeling of having my lungs filled with tar (one symptom of my depression).  I stayed on it for 2 years, and it alleviated my depression continuously while allowing me to feel like &quot;myself.&quot;  However, it did make me hungry and I gained about 15 lbs.  Worth it.  When life improved, I tapered off, and have been fine ever since.  If you try it, give it a chance.  My doctor said 60% of his patients report a &quot;light switch&quot; experience with it."
