... concentration enhancer. It worked very well. About 5 weeks ago I reduced the daily dosage to 150mg for financial reasons (it is an expensive med and my insurance doesn't cover it). Some time after that I noticed thatI'm constantly tired - from the moment I wake up to the moment I go back to sleep. It's been like that every single day and it's not only immensely frustrating but also is an obstacle to my work, where I have to be focused and alert. The thing is, that a few years ago I usedto take Wellbutrin 150mg and it was perfectly fine. So I'm not sure whether it has to do with the reduction this time. Can the reduction be the cause of my tiredness? And if so, does anyone know any other brand of similar but cheaper anti-depressants? Thanks in advance
