Hi, I Am 27 Year Old IT Professional In India,

Hi, I am 27 Year old IT professional in India, taking Nexito 5 daily, started after my break of 5 years relationship with my gf... It works very good on me.. It gives me more confidence, I tried to stop it and did for 3 monts, but got some complications like loosing confidence, lack of concentration, can not work or take preassure etc. Plz suggest me a way. How this medicine side effects on our health.
