I take Cymbalta 60mg, Evista 60mg, Omeprazole 20mg, and a few otc vitimans and supplements. I left my meds at home when we left for vacation on Friday, by Saturday mid day I had lightheadedness, nausea, sweating and dizziness. Could you tell me which if any of the meds would cause these withdrawal symptoms? I am home now,but don't know wheather to go back on these medications. It is Thursday and I am still experiencing the symptons.
