For Weight Loss (Obesity/Overweight) "Used this back in 2009. Lost over 4 stone. They are amazing. No appetite, and you feel full after a few mouthfuls. Side effects were dry mouth, some agitation, inability to keep still for long, and insomnia. If taken very early in the morning and avoid caffeine, the insomnia can be controlled. Stopped taking them due to it being pulled. Unfortunately, I have put 2 st back on! Just got some more after a long time looking. Hope to see the same results."

For Weight Loss (Obesity/Overweight) "I have been taking Sibutra Lean 30 mg for 1 month now, and I have lost 10 pounds so far. It is great and really curbs my hunger and cravings. The only side effects that I have experienced are a dry mouth and insomnia, but other than that, it really works well."

Sibutramine for Weight Loss (Obesity/Overweight) "I decided to start taking sibutramine to lose weight that I had gained last year. I chose this because you can use it long-term, unlike the stimulants. When I first started it, I barely noticed any effects (15 mg). My weight was 240 lbs starting. Then, about a week in, I started to notice a major reduction in appetite and was doing quite well. I was able to get down to 231 lbs in 1.5 weeks. Sadly, this weight loss came with major dysphoric side effects, such as tremors, anxiety, muscle twitch, insomnia, mood swings, akathisia, etc. It felt like I was poisoned/going crazy. Therefore, I had to stop it. I wish I could have continued as the weight loss was going great. Bad reactions stopped after discontinuing the sibutramine."

Sibutramine for Weight Loss (Obesity/Overweight) "Extremely effective. No cravings for anything, and even when you eat small portions, it will satisfy you. 33 lbs in 3 months, and I have a lot of energy and mental clarity. Dry mouth and some insomnia."

Sibutramine for Weight Loss (Obesity/Overweight) "I have lost 11.5 lbs in the first six weeks of taking this drug. However, the first week, the side effects were horrible (anxiety, insomnia, irregular heartbeat) until my body got used to the product. As I enter week 7 of my 3-month course, I find that Meridia is having an opposite effect on my appetite. I am constantly hungry at this point. My doctor will probably have to increase my dose for the next month. Please keep in mind that you have to do everything you can to control your own diet and exercise schedule. This is not a miracle drug, but something to get you over the hill for a short period of time until you are comfortable enough to continue weight loss of your free will. Hope this helps. Good luck to all."

Sibutramine for Weight Loss (Obesity/Overweight) "Love this medicine. I had great success in weight loss with this medicine. I seem to be in the minority who has an insurance plan that covers most of the cost, approximately $35 for one month. Side effects: insomnia and severe dry mouth, I made sure to carry gum. I have been on the medicine twice, one year apart, lost 22 lbs the last round, and it was such a great feeling. It ended all cravings, even for chocolate! Unfortunately, as soon as I stopped the medicine after 6 months, I gained it all back. I ended up with heart problems, not sure if the Meridia was to blame (I have a history of cardiac issues). I am to blame, I stopped exercising and all my cravings came back. I loved the results so much, I want another shot despite the side effects."

Sibutramine "I've lost 30 pounds in 35 days. I only experience a bit of trouble sleeping, but what I love about this medicine is the absolute aversion it inspires to anything with fat or sugar in it. Love this medication. It's changed my life."
