Feeling discouraged

Well...another new week begins. I finished week 3 of c25k training...i started week 3 again so i'm actually on my 3rd day of the 3rd week before moving on to week 4. I know i'm not ready for week 4 since week 3 is still tough. I now check my weight every monday and this morning i saw i gained a little. :( i'm kinda not surprised since the weekend eating wasn't so good- i always have too much pizza. it's soo good but 3 or less of slices should be enough but i always want more. but this time i had 1 less than i normally had last weekend. it's hard finding good lunch ideas since i want to try to eat better. i'm scared of trying new things that i might not like them. I've noticed that I don't crave sugar as much as i used to, which is good. Also, i got a pint of custard from culvers last week since i got a coupon for free pint for donating my blood last month and i finally decided to redeem it last week. I def can only enjoy like 1/4 of a pint before feeling lil sick. which is better than eating the whole thing right away and not feel so good later. i'm making it last for sure. This coming week i'm hoping to continue to drink as much water as i can, up to half my body weight in ounces and try to eat veggies/fruits. I've been feeling little discouraged since it seems like nothing is improving with my weight and eating. But i know it takes time. I'm just not always patient. I'm glad i'm able to do c25k training but i wish it's easy (i know everyone agrees/wants the same thing)!! :P Well hopefully this week will be a little better but we'll see... Till next time, Hannah
