On the trainer I drink 2l of water on the run up to a session, while on the bike I use Enervit Isotonic (about 250ml) but make it up half strength and afterwards I have a litre of water to rehydrate. Most of my rides on the trainer are 1 hour plus riding between 220-400w, weekends its 2 x 3hrs
If you need to drink that much more water on the trainer because of much more sweating, perhaps you could look into extra ventilation? Ideally there is not a pool of sweat on the ground afterwards.
