See I took it for a while..no weight loss for me but I did lost words I knew too! I just couldn't come up with them and I kept losing track of what I was saying etc. My Dr let me quick it a couple weeks ago and now I talked to her because Ive been depressed again and she wants me to take it again. If 50mg did all that to.....she wants me to just take 25mg this....its so annoying, all this.
