WLS and antidepressants

Does anyone have any experience with taking antidepressants after surgery? I am waiting to be scheduled for RNY and wondered if my dosages would need to be changed. How can you figure out if they will be absorbed differently (and need to raise the doses w/o waiting until I get depressed)? The surgeon was concerned by the number of antidepressants I was on, but this is the only combination that has consistently worked for me after years of failed attempts. Are any of you still on a number of meds after surgery and do you have trouble taking all of them?

I also take a number of anti depressants. I had my final appts prior to my 4/5 surgery. I was told that I will remain on them while hospitalized and nothing will change. After the surgery I will let you know if I have any trouble with any of them.
