It actually doesn't matter what you're on. You have the directions from your doctor right there: You must take them as prescribed in order to maintain a therapeutic dosage and get the benefit. By failing to follow directions, you might as well not take them at all.
Non-compliance is the number one reason medical treatment for mental illness fails. For some, it can be fatal.
If you're having issues with non-compliance, take it very seriously. "Being normal" has nothing to do it. For instance, I can't walk without the aid of crutches. I see people walking and running around without crutches and I'd like to do that too. I could leave my crutches home, but it's certainly not going to make me walk normally just because I did that. (In other words, it's not the crutches that make me a cripple.)
I'm glad to see you have an appointment coming up. I hope you bring up all the issues you brought up here with your doctor, because this is really important.
Good luck,
