Hi DD I saw you post in my detox thread so thought i'd stop by. I couldnt read & not post. I think your being too hard on yourself girl, if you fail one day just make the next day better. I'm sure you know that the fizzy drinks are noooo good for you, limit the fizzy drinks replace with water or squash, the carbonated crap does your body & motivation no favors!
I too had a really crappy 2009 and put on about a stone and a half, i was so shocked when i climbed on the scales in 2010 as i've been avoiding them for a while. Anyhoo i said last Monday right thats it time to get the show on the road, healthy eating, detox etc and I failed too. I woke up everyday with the intention to go to the gym, eat pure clean food but never actually went like that lol. I didnt motivate myself to go gym once and i certainly didnt eat good food but i cut back on what i usually stuff my face with. Anyway I started again today, woke up early and went gym and i felt good for it, it killed me coz im so unfit now but it felt good to know i was taking the first step in taking control - ''to climb a steep hill requires a slow pace at first''
Anyway lovie Tuesday is your Monday!! Get up, go to the gym or for a run and plan your diet as you mentioned above, you CAN do this xx
