I had the same thing with my caffeine sensitivity, but my nicotine sensitivity hasn’t gone back and it’s been over a year. I used nicotine lozenges daily for years but even after 12 months post-covid my body does not tolerate them.

Thank you for sharing. I have the same thing and it is from my first bout with Covid in 2021. I have now had Covid 4 times and the caffeine sensitivity remains along with PVCs and chest pain. Brain fog has been almost debilitating and overall the impact on my career performance is noticeable.

Have you been getting the annual booster? There is no agenda or gotcha coming, I am genuinely just curious.

Mine has never recovered. I have to drink decaf now! I feel a small amount of relief that I'm not alone.

Slow Bloom's Decaf is the best I've tried, and I really like like Savorista's Swiss Water Ethiopian too. Both can yield a passable pourover.

You can also find some good decaf black tea. Jones Coffee Roasters in Pasadena stocks some, and I'll see it online occasionally.

Related - I've been very impressed with Perc Coffee's instant decaf. Of course you can tell it is instant but it's not unpleasant at all.

thanks, I appreciate the recommendations!
