Hello, I tell everyone I can about this because it can be really bad. I have diverticulosis and sometimes it gets infected, (Diverticulitis) and if anyone else has it knows they pump u full of antibiotics. Specifically Ceprin and Flagyl. What no Dr thinks to tell their patients is Flagyl reduces the bodies ability to break down alcohol and one other important thing....... Propylene Glycol.... The bottle says to not drink alcohol but nothing about propylene glycol. What happens in a normal situation is it takes about 3 days for your body to break down PG, flagyl stops the ability to break it down and it in fact starts to poison your body. I was hospitalized with 8% kidney function due to this. Once i figured out what was causing this i both stopped the flagyl and stopped vaping temporarily. I Have fully recovered and it was just an acute issue. I am still vaping but now when i have diverticulitus i skip the flagyl. Please learn from my Issue and tell anyone you know who vapes and has to take flagyl. Hope this finds someone soon enough. Best of luck out there.
