I agree with just about everything in that post.
Tolerance is unavoidable with regular dosing, but if you cycle your dosage amounts, and take regular breaks (not necessarily cold turkey for weeks at a time, but a few 3 day segments a month at half your normal dosage, or micro doses to deal with mild wd symptoms) it works out pretty well. I've never had a problem w/ opiates, and save a few morphine/hydro experiences under medical supervision, i have no classical opiate tolerance.
So long as you don't get into a long term habit of taking the same large amount, or increasing amounts daily, and get a handle on your tolerance a few times a month it works great for so many purposes. They say cannabis is the most medicinal plant known to man, and i tend to agree, but kratom definitely gives it a run for its money. Depression, pain management, anxiety, opiate abuse maintenance, mild stimulation, hypertension, etc.
All i can say about paypal is fuck those bastards. They are not a bank, and can do whatever the fuck they want with your funds, and who you choose to buy from (so long as its legal products, like kratom). They're kinda like the DHS/Customs in that they can operate outside the law in regards to enforcement of their services. I avoid them at all costs, save for ebay. My favorite vendor uses dwolla, and i'm going to be a loyal customer until the day kratom is banned/controlled, or he takes a well deserved cash out and retires.
