If you are on antibiotics for a chest infection and start drinking again when it clears, will alcohol cause it?
That’s a difficult question. Of course it depends on whether we’re talking about a glass of wine, or a whole night on the town, out in the cold, bad food and getting absolutely p*ssed. In the first case, no it won’t return because of the alcohol. In the latter case, yes it will probably return because after an infection your immune defenses are down and putting yourself out like that will make you very vulnerable to having the infection return or another illness come.
