Just wondering if anyone suffered side effects taking this, if so did they last or wear off? I've just had my dose increased from 100mg 3 times to 200mg x3 a day. At the moment I don't feel like me at all - I feel really quite low and sleeping at every opportunity and not enthused to do anything at all. When I first stated taking this - I felt exactly the same for about 3 weeks, it was horrible then and it's horrible now. It has helped with certain things, but I'm not sure what is worse depression or neuro dysfunction, I always quite liked having my fuzzy wits about me, now I just feel like a slug!!
