I have been taking Kratom
) for about 4 months at-least once daily (Usually 2-3 times a day). I have found re-dosing to work very well for me personally after the first initial dose. I do notice tho the first dose to have a slightly stronger effect than re-dosing does, but re-dosing was found to work very well as-well (And I almost always re-dose after the initial).
For me, currently with my tolerance, Kratom kicks in fully in 30 minutes for me on an empty stomach and fades away after about 2 hours. In the beginning of my Kratom usage (Before I began a tolerance to opiates
at all) I remember the same on-set as noted above, but the duration was maybe an hour longer.
I currently eat 10-15 grams daily, but I have had my usage go up to 25-30 grams daily before. I only did this for roughly a week and ran into problems with constipation and it was difficult to eat enough food to stay at a healthy level. I also found the effects to be overall much more enjoyable at lower dosages and also much cheaper money-wise.
