Are sports drink like Gatorade okay when intermittent fasting?

I'm currently doing 18:6 intermittent fasting. My fasting timeframe is 8pm to 2pm and my feasting timeframe is 2pm to 8pm. I exercise during my fasting time, around 1 am or 2 am after work because it is the only time I am available to do so. My concern is that aside from water, I can't help but drink Gatorade (but just a small amount. I don't finish a while bottle) during workout. Is that okay?
