Hi @TaraJ that’s sounds rough - I didn’t experience constipation, had more trouble with diarrhoea.
Not sure if you’ve been prescribed Ondansetron (one of the anti nausea medications) but the nurses told me it can contribute to constipation and a way of countering that (aside from all the other good tips above) is to also take the other anti-nausea medication Maxollon, as it can have the opposite effect. Really hope you don’t have a repeat of your last weekend in hospital, sounds no fun at all.
