Ohhhh man, I remember when I had that. For months coffee and most energy drinks tasted like complete bitter garbage. I remember that with Reign too. I like Peach Fizz a lot btw, and I’m not a big peach guy at all.
Also, start taking 1-200mg Niacin/B3 daily. Clears up long COVID fatigue/brain fog symptoms in a very short span. Most people begin feeling better in less than a week. COVID hyper-depletes B3, and when it hangs around it can create this vitamin deficiency. Also, don’t buy higher mg amounts - 500mg of niacin will produce a terrible flush. You want to order 100mg caps; they’re like $5.
