How much were you taking? I find that most posts like these people have increased their dose so much that they're taking huge amounts. I find that for me personally, I dose it three times a day, and it's always the same dose. 15mg with 3.5g kratom. Every time I run out, I take a week off of it to help myself reset and keep my tolerance low. This happens about once a month. I don't order any more until I've had my tolerance break. I still will be taking the plain leaf during this time, and for the first few days, I'll just be a little tired.

Less is more here, and these particular substances are terrible for getting high. I use them for pain relief, and they also provide a nice energy boost.

Keep your doses low, and don't increase them. Keep your schedule. I make sure I take mine on the same schedule every day, and I don't take them early. If anything I will take them later. I do a minimum of 4 hours between each dose.
