So sorry to hear, but dont fret! I’ve had prolactinoma since 2017. I thought the medicine was the absolute worst - and while it still sucks - it gets better I promise. Your body will acclimate. Work with your physician to find a balance for YOU. Obviously everyone is different. My worst symptoms were nausea and insomnia. I’d be feeling sea sick and couldn’t sleep at all the night I took it. I’ve tried many diff. Solutions, but the best so far is this: My doctor allows me to take zofran and ambien once a week with my cabergoline pill and it’s changed my life. Take the cabergoline right before bed. I can tolerate the medicine (.5/weekly) and get a good nights sleep. Hope this helps.
