Anti-depressants Post Op Absorb

I had my surgery April 2004.Currently depressed taking Meds but don't seem to be working. Sometimes I just pass my meds without absorbing them. Went to my doctor and she told me there was nothing she could do, that I would have to go back to my surgeon regarding absorbtion problem. Now I have been referred to my primary....... Can anyone Relate? or have any sugestions.

try taking them with a warm liquid Ie coffee or tea
