I am going to attempt (again) to stop taking my meds. I have been prescribed these for over 10 years now.
When you find you are a taking a drug just to feel normal, things need to change. 
Sometimes prescribed medication can build up in the system, such as my mother's stroke medication. I told her to break the tablets in half. But I think to go cold turkey without seeking the advice of your GP first is rather drastic.
I'm not sure I believe in New Year's resolutions but I should eat less sweet stuff and look after my teeth.
