, you could go to the thai consulate in Savannakhet and apply for either a 90 day single entry Non-O visa or a year-long, multi-entry Non-O visa based on marriage.
the year long visa would require you to exit/re-enter the country every 90 days.
If all you're wanting to do is "start over" so that your money can season the 2 months before you apply for the extension, just go to Savannakhet or Vientiane and get a 90 day single entry Non-O visa.
