So some of you who have been following my threads know that I was back on Wellbutrin and it caused insomnia. When I went to my t about it she changed the Wellbutrin to the "sr" form and prescribed seroquel for sleep. Now I feel the dr isn't as effective in treating my depression. I felt a relapse of sadness. Today I took an xl and feel great and have energy. What should I tell my t, cause I think I'm better off with the xl than the sr. Can someone also describe the difference? Thanks for your help.
