I was coming off Cymbalta and, after 2 weeks without it, was having horrible withdrawal symptoms. I saw my doctor yesterday and she added Wellbutrin SR 150mg for the morning and cymbalta at 20mg in the evening. I feel shaky and my heart is pounding heavy in my chest. Can anyone tell me what they've experienced, if it gets better, and if Wellbutrin is helpful? I've missed work as a result of withdrawal from the Cymbalta and desperately need something that will fix this.
