Just took advantage of the Halfords High 5 race pack deal, having been caught short a few times in summer and had to dive into a shop for jelly tots 
Didn't quite realise how much stuff came in it (pretty amazing deal tbh) and now I have gels coming out my ears, which is fine. But I read quite a lot of people get stomach cramps/diarrhoea/vomiting when using gels and energy drinks.
Have you had these problems, and in particular with high 5 stuff? How can it be avoided?
Cheers
