interesting! i asked my doctor if i could go on citalopram as well but he said that my 50mg desvenlafaxine with the 0.5mg diazepam would work well enough, and we would increase the diazepam slowly until i go off it in a month to avoid the negative side effects of taking benzodiazepines. did you find it took a while for it to kick in on your stuttering or did it improve almost immediately?
