You buy the minibus ticket at a travel agent, B650
You get picked up at around 7.30am from your residence
You sit in the bus for about four hours with one quick break
You get to the border, go through Thai immigration to get out
Go through Myanmar immigration; there they just want $10 or B500. They give you a card to go into Myanmar so you can go shopping for all sorts of crap in the market, although wines seem cheaper (and the labels look suspiciously new)
You return and pick up your passport, go to Thailand, fill out the arrival card, and get another 3 months
You get on the bus and head home
Not the most exciting day of your life
