I don't think you're really losing faith in the sense that you doubt Allah.
I think you just wish you didn't have a faith and could do all the forbidden things you want without feeling guilty. Do you know how many non-muslims also feel guilty after wasting their lives, sleeping around and doing things they did without fear? Too many.
If Allah forbids something for us, it's not for His benefit. It's purely for our sake. Look at the harm, the things you want to do, can bring to you. It's not worth it is it bro? :?
Here are some pictures of cancers caused by smoking.
Lung Cancer
Oral Cancer
There are four factors that appear to increase the risk of developing oral squamous cell carcinoma:
(1)Tobacco AND (2)alcohol--When indulged in together over a long period of time, heavy alcohol and tobacco use are the most potent physical factors contributing to the development of squamous cell carcinoma. Those who both smoke and drink heavily, have a 15 times greater risk of developing oral cancer than those that have neither habit.

I'm sure smoking and drinking seemed appealing to these people once. But now they wish they'd never touched them. Alcohol also leads people to commit haram acts. There are tons of pictures of sexually transmitted diseases which you do not want to see. It is worth risking years of pain and suffering, humiliation and even death from cancer/stds and more, for a short time having 'fun'?
Allah has only prohibited us what is harmful. Allah has created and made permissable so many things for us and then created even better things for us in the Here-after - if we avoid what He forbid to us in the dunya. You have to be aware that the shaytaan makes the haram desirable to us because he wants our destruction. You must fight your innerself and put your mind to better things that please Allah.
All you have to do is seek protection in Allah from the shaytaan, strive to fulfil your obligations and ask Allah to lead you to a purpose in life. This life my brother is on average between 60-70 years? Compare that to a life of eternity in Paradise or Hell. Big difference isn't it? Where do you want enjoy it?
Whether you take heed and restrain yourself from the things Allah prohibited or not. You will return to Him. Everyone at their time of death, knows there is no turning back now. All your paths will finally take you back to Allah. I really pray you are from those who return to Allah having earned His pleasure. Because nothing will save those who have earned His anger on the Day of Judgment. Allah is Most Kind and Merciful but you also have to strive not to bring ruin upon yourself. May Allah preserve you. Ameen.
