Im confused i have been told different things by different doctors. Some say you can become immune to an anti-depressent others say that its impossible for a anti-d to stop working/become immune!?

What do other people think?

Ive been on Seroxat for 10 years and i really dont think its working for me anymore, i also have had to have the doseage increased to the maximum amount until i got the same effect as a lower dose in the past. So have i answered my own question? LOL!

Thoughts anyone please? Im very confused xxxxx
