you could probably get away with it because thats no where near the limit of overdosing on ALA. But you will suffer from extreme heart burn. That much ALA at one time will definetly hurt. I've taken as much as 3-4000mgs at once before a big carb up meal and i got heartburn from it.
If your determined to take a total of 30,000mgs i would suggest starting off slow with it. take a max of 7-10,000 the first month and see how your body reacts.
