I have been taking Zoloft for about a month or two now, and have been noticing that I’m not sleeping so well. I just bumped up my dose to 100mg three days ago. I’ve been waking up with a feeling of my stomach dropping and just panic honestly, almost like those dreams when you wake up when you’re falling. I’m rather concerned since I haven’t been able to sleep for more than 2 hours at a time and night. I’m being treated for anxiety and depression.
