I am a college student and my doctor prescribed Effexor to me to help with both ADHD and Depression. I started out over the summer with a dose of 37.5and then increased it to 75mg. I have recently increased the dosage again because it was helping but I was still very anxious. I was constantly crying and I still couldn't focus on my school work. I am currently on a higher dosage and it is 112.5. It says that the symptoms cause you to eat less but I feel like I am snacking more than usual and I am finding myself exhausted and sleeping for hours when I had already gone to sleep early the night before. Is this normal when increasing the dosage? I am actually concerned with my health because I do not want to gain weight because I don't have enough energy to exercise and I don't want my grades to suffer.
