Congratulations on your quit REnglish!!!
No, I could never have quit for Lent. I had to quit for ME, and that was a tough decision point to reach. However I'm happy to say I did it. Over 35 years of smoking was way too much.
If you quit for Lent, then power to you. Quitting smoking is one of the best things you could have done for yourself. HOWEVER, I do not recommend going back to smoking when Lent is over!!!
If you really want this to work, then you can never take another puff.
Best of luck to you!!!
