I started using Kratom about 6 months ago, taking 2 grams about twice a week with excellent results. About 6 weeks ago, it seemed to stop working so I investigated and found that storage is crucial and mine was probably inadequate. So I threw it out and got some more which worked for a couple of doses but has now stopped again even though I am keeping it in the fridge in small airtight bags in a jar. Should I switch types? (I am taking red vein borneo) or increase the dose or switch to capsules? or all 3? It worked so well before and I am loath to increase the dose but any comments or suggestions would be very welcome.
