every 4 hours all day long is already kind of crazy and you are on your best way to get insanely dependant on kratom. personally I use 2-3grams in the morning via self-filled capsules and sometimes a lil toss-and wash to help with sleep in the evening. you should definitly limit yourself harshly on what your MAX dosage a day is and never go over that. otherwise its a slippery slope into addiction real quick
