Brain fog, chatty kathy, spacey
and just plain stupid, no appetite, tingling,
and insomnia. I went from 50 to 75mg, 5 weeks later and 75 to 100mg 4 weeks later, working up slowly does help with the side effects. Over time I have found most of my side effects subside: I take it for nerve pain and complex migraines. Certain side effects have stayed: anything carbonated taste awful, tingling in hands and feet, small twitch in left eye for last week or so.
