This is just my 2 cents and experience but I though it best to share. I have used Fent er mean for a number of years as I had a weight issue that I got under control but continue to use it for maintenance. I have actually been using a Mexican product called Ax zeon for a number of years as I used to live close to a border town in the SW of USA. That being said, on one of my trips down, the whitecoat told me that I should try Clobenzorex (since he was out of my 1st choice). Said it was better acting and very popular for weight loss. I went ahead and got a small supply and committed to myself that I would research the product and if it all looked ok, I would try it. It looked legit and so I began to take one per day to see if it would curb my appetite as well as provide the additional benefit of an energy boost which I appreciate. After a few days of use I began to notice that I would slur my words at time unless I concentrated very hard to enunciate clearly. I researched some more and found that this was indeed a possible side effect. Never took them again and they went for a swim down the porcelain water slide. Your experience may be different. Anyone else had a similar or perhaps, different experience?
