Yes , smoking is quite injurious to health . I would rather suggest you to quit smoking. Smoking or consuming nicotine is a kind of physical and physiological addiction , where our body once gets used to does not let us stop it . Smoking done at a high rate (many times) could be quite injurious to health in many ways and depression
,nausea , tiredness
are its withdrawal symptoms
.So i would suggest you to reduce smoking and eventually stop it for a good health.

drug , and it should be taken under monitoring and guidance of an medical expert
. Over dosage of this drug may lead to may health issues be it from digestion to reproductive issues. Hence please make sure that the dosage has to be carefully monitored.

If you experience any further issues i recommend you to consult an physician immediately.
I hope you get well Soon,
