Definitely congratulations on your amazing weight loss progress! Keep it up! Yes likely you wont ride Millenium Force, Wicked Twister, or Top Thrill Dragster right now but if you keep losing the weight like that then you may be able to by this time next year!
And if not for riding coasters, keep on losing weight anyway just for you! I myself have lost 45lbs too, but I too likely wont make it on those coasters yet either. But I am going to work my @$$ off to get as slim as I can in the meantime and hope for the best.
Good luck and best wishes!
I, too, will congratulate you on your weight loss, but will have to agree that Millennium Force, Wicked Twister and Top Thrill Dragster are out of the question. I cannot say, NO, you will not be able to ride, but from your description, you probably wont be able too.
How tall are you? That could play into things also. I hope everything works out for you, and again Congrats on your excellent weight loss!
