I noticed I felt "something" after the first pill, but it was probably 3-4 days of 2x daily dosing before I could tell that I was in much better control of my eating. I think the literature says it takes 3 days to reach steady state, where there is a consistent concentration of the drug in your system. So, I am guessing that is why it takes a few days.
I'm providing an update since I can't see how to add to my original post. I continued taking the Belviq for 9 days. I am going with the assumption that I am a non-responder. I know what it is like to lose the hunger and craving temptations COMLETELY, as the FIRST time I took Phentermine that is what happened. Had I of known then that Phentermine, for many, loses its effectiveness after the first time, I would have worked my butt off for the 2 months that it worked. I did lose 20 lbs at that time quite easily but then the effectiveness of Phentermine wore off and every time I've tried it since IT DOESN'T WORK FOR ME.
Back to the Belviq - Doesn't curb my appetite at all! I've read where ONE person became a responder after 14 days but it seems most of the people here are responders and it happens quite quickly. I did not wish to continue to Day 14 or 15 (I went to www.belviq.com and signed up for a FREE 15 day voucher that you print out and bring to your pharmacy) as the only side effect, or only effect at all, was that Belviq was making me forgetful or "dingy". I just started a new job 5 mos. ago so I decided that I would move on and try something else or just write down my foods and exercise like crazy and eat the 1200 calories per day that the dietician I just saw advised me on to lose 1 lb per week!
Good luck to everyone that Belviq works for!! Maybe the Phentermine will work again for me one day and I can easily and effortlessly lose weight also!

Been on Belviq since Jan 2, 2014. I have not experienced the huge losses, but have lost 9 lbs in 3 weeks. And based on the facts of biology, you really shouldn't be able to lose more than that -- otherwise it is muscle or water. Belviq has worked for me to take away the cravings I had for breads and sweets. I don't feel compelled to go eat when I am frustrated, but its still a little there in the background. Someone said it works on your subconscious desires to want to eat. I still have to track all my calories (myfitnesspal.com is great) and my exercise (use fitbit-links to myfitnesspal) 1-2 hours of walking a day. I still have had to create a lifestyle change. But it helps you to be more successful at doing it. For me, it's great to "feel" like a normal person and not have the thought of food as my daily priority.
