Corona and resume smoking. Of whiskey?

I had symptoms of corona like 99.5fever loss of taste and smell and foreheadache and little sore throat.  Rtpcr came as negative and it's been 12 days since the day I got fever the first time. Took sinarest and Azithromycin and montek LC for 5 days and Ivermectin12mg for 3 nights and now I feel fine and it's been 12 days and getting cravings for smoking maybe withdrawal symptoms and I smok d around 2-3 cigarettes only per day. I didn't had geve from 4th day and had no coughing or breathing trouble. Hope my lungs is not affected. I am continuing zinc, lymcee, a2z gold, cod liver capsule and hot water steam 2 times and drinking luke warm  water. Can I start smoking now with just 1 cigarette a day and can I drink occasionally maybe 1 beer or 2 pegs of whiskey? My weight is 67kg and r meat all reports came normal including IL6 ,cbc, and d-dimer. Please let me know if I can smoke 1cigarette a day and can drink a beer once every week.
