Bupropion

I was prescribed this to quit smoking. Nasty habit I KNOW. I’m just as mad at myself. Anyways it’s only day 3 and I’m crying. I take 150 mg but tomorrow supposed to switch it to 300 mg. And I’m just emotional. Like 100% a crybaby. I just wanted to know if anyone took it and had a similar experience and maybe overcame that. Like will it go away after a few days? I wanna stick it out and see if maybe it’s cause it’s a whole new medication but wanted to know if anyone had funky experience at first and stuck it out.. I’m sooo eager to quit smoking and really read how good this medication works on that aspect. But just want to hear others experience?
