DONT fucking jump from 375mg to 1000mg. dxm trips go in plateaus, and for someone ur weight, 364mg is a low-mid second plateau trip. the third plateau is VERY different from the second, and im not certain, but 1000mg is getting close to the fourth plateau. take maybe 550-600mg for ur next trip, and if that isnt enough, then progress, going up maybe 75-100mg each time. i really wouldnt suggest jumping that much in dosage
