Each time you do that your brain has to find its equilibrium because you aren't naturally producing the neurotransmitters anymore. What you're experiencing is probably withdrawal symptoms, especially if you're cold turkeying the medications and you're on high doses.

If you're going to take medication, try to commit to it for x amount of months..perhaps 6. Then evaluate the effectiveness of the medication with a therapist/pdoc at the end of the period. During that period if the medication is just not working then speak up so you can change the medication and reset your commitment. This will keep you on medication long enough to decide if you REALLY want to stay on it or if you hate it and rather go without. It can also help you figure out if the medication is actually working long-term or if it isn't.

You can also look into alternative lifestyles or learn coping mechanisms from members here. You don't necessarily need to take medication if its not for you.

I know that you quoted "normal", but if 1/5 (maybe 1/4) individuals are reported to experience mental illness at any given time. I'd say that we're a growing minority. I used to believe taking medication would help me normalize, but then I realized I'll be a weirdo for life.
