I can relate to your feeling sick due to lack of sleep...cumulatively. You can take it for a few days but, after that, the loss of sleep hours start to add up. I recently went through a period like that. I know SSRIs aren't indicated as a proper treatment for those who have bipolar, but it does tend to give me a bump out of depression. Anyways, once I went off Trintellix (a SSRI) my problems seemed to even out. I always have trouble sleeping this time of year, but extreme sleep deprivation is a dangerous thing. If you fear you're having too hard a time with it, a short IP might help you with your meds.
