Hi Rachael

Welcome!
I'm a new starter too and was in a similar boat to you just yesterday. I jumped straight in and decided to fast my first fast day but like the people above found that as I ate soon after I got up it made me more hungry and it was very difficult. Personally, I gave up though actually ended up eating a lot healthier and a lot less than usual! Added bonus!
Today I didn't have anything in the morning except some sugar free squash. Am the kinda woman who needs a lot of milk in her tea/coffee so avoided that particular option. I also felt more mentally prepared... partly I guess because I now know what bits I found the hardest about yesterday... my weaknesses, if you like.
And thankfully today has been pretty damn good so far! Planning a nice early night as well.

I think it definitely will get easier for you (though I am of course not speaking from experience). Maybe take it a little slower and start the next day when needs be.

My experience is that beating yourself up for anything (whether hunger or having to start something afresh or whatever!) is not all that helpful so if you're not already, just be as kind as you can to yourself!
Lots and lots of luck and moral support. Let us know how you get on.
