I'd go with Wild Coyote's/Shazerac's advice & start the meds again - as well as losing the help of the meds, your body may become accustomed to them & is struggling more because of that. Additionally, some meds take a while to fully exit your system, so it might take less time for them to start having an effect again.

Did you have any luck with that email? I think that they generally respond within a day.
