I retired at age 50 with about half of what you have saved. I haven't had to change much in my lifestyle because of the reduced income from my investments, which by the way are doing VERY well, each year my account grows while taking around 7% for income. Ive been retired for four years now, and I hope I never have to go back to work. You should be able to get a very nice annual salary from your savings and never touch your principal. If your investment advisor can't provide you with that I would look elsewhere, there are even some plans with guaranteed rates. You will be ok, just do your homework and deal with a reputable company. Some guys that retired about the same time I did, dealt with some questionable firms and are now basically BROKE, be careful.
