My sense of smell didn't come back 100% and it's been 13 months since I first contracted this virus (didn't bother to check but the symptoms all pointed to it). Sometimes I can smell properly, most times not. The second time we got the virus a couple of months back was a lot more manageable than the first one. But yeah, the cough was the most annoying part apart from the fatigue.

Hope you get back to your 100% soonest!
