I have to pyramid-up into 5g a day....otherwise, it's bad news for me too.
But if I take it slowly at first (I'm at 3g/day this week), I tolerate 5g/day OK and all I miss is that "loading phase" which is only a factor if you're in a hurry.
FWIW, my gym had a chart on the wall for years about the benefit of supplements vs. cost (from Flex or M&D), and by far, the number one on it was Creatine (they weren't including whey).
Boring...but apparently helpful for muscle hypertrophy...your mileage will vary...
