I found that if I use a smaller plastic cup and fill it 80% full, there is still enough room to manually shake it and mix the water and protein and I didn't get gas as a result. The manual shake method does settle out though, so I shake them twice, once when pouring them into the glass and once right before consumption.
Hope that helps.
