I am at my very wits end with ongoing colds and coughs. Since 2021 I've had so many coughs and colds I can barely keep track of them! My DS who is one has just started nursery so I know it's only just going to get worse. So far I am religiously taking my vitamins, not drinking, upping the exercise ( when I'm not sick!). Any other wise tips that have miraculously turned around your immune systems please :-)
