Meditation/ Mindfulness etc

So I "think" I suffer from stress, both work-related and from other real-life things I have very little control over.

I also have a physical problem: random twitching of muscles that one doctor thought might be stress-related. It's not that serious to my knowledge, but it is annoying.

Can people give me input on whether meditation helps in some capacity? Is it worth getting into? When/how often should I meditate? Please share your views or stance on it.
