The nausea and dizziness were unreal. The weird anxiety/
sleepiness combination, too. Sometimes SSRI ( like
Paxil) cause these precise side effects at the beginning of treatment. When will you feel better? Check the half life of Paxil. Just for example, the half life of lexapro is 32 hours and it took me 3 days to go back to normal after a single dose.
Of course, I'm not a health professional, just a fellow anxiety sufferer. By all means, call your dr and tell him how you feel.
