Welcome to 3FC =)
I'm a Weight Watchers member, and if I could say anything to someone who is curious about joining the program... it's "Go to a meeting. Get there early, stay for the whole meeting, and afterwards stick around to listen to how the program works."
They go through promotion phases where joining is free or very cheap. You -might- (depending on the leader) be able to sit in on the meeting before deciding. Or you could join up for the day to sit in and see what it's like.
I have to say that the accountability, the support, the encouragement... the
understanding of the people at meetings is worth it. I'm sorry to say that meetings are not a regular option for me at this point in time, but when I lost 100 pounds I went to meeting
every single week. I had an amazing leader who was quirky and wonderful. I made friends at the meetings and we got to talk about how the week went or the choices we made. ... There's a reason I frequent 3FC so heavily. I am a person who NEEDS support for this. I need the accountability. I need to see other people succeeding.
I'm not very good at long-term projects, either. I start out ambitiously and then never following through with all sorts of things!
However. I'm human, and the greatest thing about being human is that I can decide to change a behavior. Do I still make mistakes? Tons of them. Doesn't matter, though. The only thing that matters is I'm still HERE, making the effort and I have changed for the better.
Before you can decide what you need, though, you'll want to actually try it out. If you find after some time that you can follow through without the meetings, then do so. There's no wrong way, as long as what you're doing actually
works for you.
PS - If money is tight, you may want to considering using the WW Online version which is MUCH cheaper. You can then use their boards as well as the 3FC boards to help with accountability. I still highly recommend going to at least the first meeting to help see how the program works, though.
