I was prescribed Lexapro 20mg a while back and stopped taking it because I was a really dumb kid. I have really bad anxiety and a terrible fear of being sick (emetophobia) so I've been looking to start taking it again. However, I know that taking 20mg straight away will probably give me awful side effects.

The pill itself has a score line down the middle so I would assume it's safe to cut in half, I just want to know if cutting it in half will make the dosage 10mg rather than 20mg? Which would in turn lessen the side effects. As I'm absolutely terrified of being sick, but I know I just can't live like this anymore with all the panic attacks I'm having every day.
