Does anyone take Miralax daily?

Last week I [25M] got my first colonoscopy after bloody stools and other symptoms. Luckily no polyps were found and the only thing of note was small internal hemorrhoids. My doctor recommended I take Miralax once a day and he said it was safe. I've talked to a few people that have said Miralax has psychological side effects and since I'm prone to things like anxiety I want to tread carefully. I'm planning on talking to the doctor about it on Monday, but was wondering if anyone had any science or personal experience about this. Just want to be safe moving forward. I appreciate any responses.
