Hi Will - by all means, this is great - if it has worked for you in the past - it is definitely better to go back to something your body responds !
In all of my experience - I have never had a problem of restarting any antidepressant to regain the same positive effects. I have done this with at least three or four different antidepressants.
By all means, get restarted on them, on you have your answer in 20-60 days (usually sooner, since you this has already proven to work with your body).
Hope this helps, let us know your progress
