Hi! I just had my aortic valve and root replaced with a mechanical valve + conduit a month ago.
As far as lifestyle goes, we have people here who ride motorcycles, do manual labor, and lift very heavy weights at the gym and they are doing just fine. A woman climbed to the top of Mt. Everest with a mechanical valve. Realistically, there aren't any absolute lifestyle restrictions just for having a mechanical valve. You should just be conscious of the risks of a given activity and take the appropriate safety measures, but people should be doing that anyway.
In terms of diet, cranberry juice and grapefruits are the only common things I've heard to avoid. Other than that, there isn't any dietary restrictions. The main recommendation is to just keep the amount of food you eat with Vitamin K in it (dark leafy greens, broccoli, herbs, etc) fairly consistent from week-to-week. You shouldn't avoid those foods, and in fact there is some evidence that consistent Vitamin K intake can help to stabilize INR levels. I don't drink but many people here do without any issues.
It seems to me that the perception of the risks and "lifestyle modifications" associated with mechanical valves is overblown by some people (and medical professionals.)
Edit: Also, personally, the ticking is very minimal and I don't find it to be a problem at all. If anything, it's reassuring. And this is coming from someone who is sensitive to certain sounds and sensory over-stimulation.
