I started prozac 4 days ago. 2 hours after taking the first pill of 5mg i had a panic attack, took zanax as per my doctor request. The whole day i felt sleepy. The second day i wasnt that sleepy, but got 2 panics. The third day was fine during the day, but woke up during the night from a severe panic which go me shaky for 40 min, took zanx again and have been sleeping almost the whole day. Today is my forth day on the pill and talk to my doctor. She sad the side effects will go away after 10 days. But i am just wondering if they will ever go away or i need to try a different medicine. Can anyone experience something similar like this. Please give me your opinion and thoughts. Thanks.
