I started 150mg XL Wellbutrin a week ago. Jitteriness is a side effect I have. Worse after 1 cup of coffee which is all I drink in a day. Insomnia is also a side effect I am having. Go to bed at 1100pm, awake at 1:00am, back to sleep til 3:00am then awake until going to bed again in the evening. I am reading from may people these side effects will fade, Will they? How long roughly will I feel this way? When I started the Wellbutrin I was taken off of my Cipralex which I had taken for quite awhile but found it wasn't working. Thank you.
