I did it about 8 months ago and it wasn't hard at all. I love being a vegan!
There are so many "replacer" products available now days that it doesn't seem like I go without anything that I enjoyed when I was a vegetarian. For example, instead of dairy ice cream, I have Tofutti soy icecream or cocolicious coconut ice cream. Instead of cheese, I can make cheese with cashew nuts, or I can buy dairy-free cheeses like shreeze, cheezly or daiya. There are lots of milk alternatives available - soy, almond, oat, coconut, hemp, rice or quinoa (to name a few).
When it comes to things like pasta, I usually buy a wholemeal spelt pasta and if I am eating out and wanting to order pasta, I always make sure that the pasta has no eggs in it.
I didn't really eat eggs before I went vegan, but there are egg replacers available. I do enjoy scrambled tofu now days when I go to vegan cafes for breakfasts - it's delicious!
There are lots of mock meats available, but I don't have them often. I sometimes use a soy protein when I want to have a mock-bolognaise, but this is rare.
I'm happy to answer any questions that you have. Since going vegan, I've lost about 10kg (about 22lbs). My asthma has gone, I have lots of energy and I feel so good. I have blood tests every ~3 months to ensure that I am getting enough nutrients.
It took me about 3 weeks to find my groove as a vegan. I had to really stop and think before I went shopping or before I made anyting. Now days, it's all so normal for me that I don't even need to think about it.
I hope it works out for you, it's one of the most rewarding decisions I've ever made.
