Hi,Sreekant,thanks for query.You have take hard decision to quit smoking
,at a time.There are no ifs and buts.First of all cut down heavily frequency.Then if needed you can use nicotine patch
after advise from your doctor,this is to avoid withdrawal symptoms
that you might have.It is always good time to quit smoking at any age.Please be firm,make up your mind and go for it.
wishing you all the best.
