Hacc, I have had a sad history of late with nausea - and not only when running or riding. I will get back to my own stuff shortly. As for some suggestions/questions above. Perpetuim may be a viable solution - a lot of people swear by it. And for running, those gel flasks works a treat and you can mix it like a batter consistency and drink your water separately. (A thing I started believing in of late is to separate hydration and nutrition...) Sachets - I tend to use a bit at a time. I utilise the gel in 2 or 3 sessions, just before a water table. Roll the open end and put it back in my pocket. First off, my issue was diagnosed after all kinds of probing - and it was due to my gall bladder removal. Now, years later, it sometimes happens that the gall pushes back (esp overnight) into the stomach. I now drink something for that and 90% (maybe more!) of my problems are sorted. Things to also consider: a lot of the times nausea is caused by not enough water relative to nutrients, so your gut wall cannot transport it quickly enough, esp in low blood supply times. This is greatly why I started separating hydration and nutrition, to keep better tabs of what I actually put in. That is also why I like gels and easily digestible things - the less stress I can put on my stomach, the better. That's my 2c. Having shot my mouth off, I'll most likely loose my breakfast on my next run...
