I am adicted to Smoking which caused blocks in my Veins stopping the free flow of blood inturn troubling me to walk and almost become impossible to run. I am smoking since 9 years now and smoke atleast 20 to 25 cigarettes day on an average. I am now trying to quit smoking but find it very very difficult. hence approached one doctor to help me quit smoking. She suggested couple of Drugs. 1) Clonotril 0.25 and 2) bupron XL 150. Not sure what it does. Like to hear from you if this medication helps me quit smoking and what are the fucntions of these drugs. Also would be great if you can help me know - if there is a way to get my Veins clear in otherwords getting rid of the blocks in my Veins.
