Advice:Excessive masterbation medication

Hi, I've been masterbating atleast one time for about 10 years now, somedays 2-3 times. For this, I consulted a psychiatrist he advised me to take Setral 50mg in the morning and etilaan 25mg in the night. But I didn't know these are antidepressants, have read about it online found many side effects. Also, I did masterbation today morning, didn't enjoy as I was enjoying earlier and also my libido dropped significantly.  I have taken 4 etilaan 25mg and 4 Setral 50mg till now. How long these tablets affects will be there?. I know my excessive masterbation can be controlled by myself, I've also started to go gym and will be joining yoga and meditation class in 2-3 days. I want to discontinue taking these antidepressants. Any help on this would be appreciated and happy consult online.
