Effect of bupropion XL

I took bupropion for almost 5 months from January 2014 to May 2014. The comedicines I took were zincovit tablet, mega-3. Initially I felt more energetic and motivated. After 3 months, I did not feel enough motivation and energetic. I used to feel more sleepy. Along with this combination, I took calmagzinc (21st Century brand - calcium, magnesium and zinc). I felt severe headache which lasted for three days. The headache did not go even after taking paracetamol or aspirin. It went away after stopping calmagzinc. So, it appears that magnesium may affect dopamine synthesis and release by inhibiting the glutamatergic neurons.

Also, I read that all antidepressants impair the quality of sperms in males by affecting the DNA and other parameters (motility and count). Bupropion also is reported to affect sperm quality.
