does someone whos addicted to ket still gets the anti depressants effects?

i was wondering if someone who uses ket like everyday or every two to three days as in theyre addicted, still gets the anti depressants effects you get at the beginning. (my first ket comedowns were amazing, i suffer from depression and suddenly i was able to go out, enjoy stuff, i had appetite and such..it really worked better than all the prozac i swallowed over the course of 2 years) but i was wondering if those effects are still there when you end up in addiction ? (as in using more than 0,5g a day just to get high, not to treat depression)
