Yup that is what people call em. Brain shocks. I went cold turkey from 300mg because the place that sent me my meds for free failed to tell me they were out of stock. Yet I got an automated message saying it was being shipped. I went 5 days without it and then had to buy two weeks halfdosage to hold me over. I never went back to full dosage. Ef that. I am not running out of meds again.
