Its hard finding the motivation to diet before the surgery.

Perhaps baby steps during those time would help?  One week give up sugar, the next pop, coffee, whatever your demons are.  Perhaps start replacing breakfast with a protein shake for a couple of weeks and then start replacing your lunch also with a protein shake?  That way when you have to start the preop diet, if it is full liquids all you will have to do is give up dinner and you won't feel deprived of everything all at once.

I am slightly concerned that you stated you 'just need to stay focused for 3 months.'  You actually need to stay focused for the rest of your life, or you may have problems after the surgery.  You may not have intended your statement to come across that way, but I also want to make sure you don't have any false expectations about what the surgery is or isn't going to do for you.

To take your mind off of the dieting aspect, perhaps you could turn your attention to the working out aspect.  That way your heart, etc, will be in the best possible shape before the surgery and you may also lose some weight.

Wishing you the best in your preop journey,

I did sort of mean that, but I know that after I get the surgery that I will phsically feel full and I think it will help me alot stay on track after that. I do want to eat right after the surgery and make good choices for the rest of my life. I just feel like RNY will be the greatest tool to help me get there.
Baby steps sounds like a good plan. I gave up chips a week ago but I did have some one time.
Today is soda.

 I started my journey in MArch of this year, and began a low carb, high protein diet at that time. I had to lose 20 pounds before they would even schedule surgery. Once I hit that goal, I allowed myself one meal once a week that was a total "splurge". Pizza, sub, pasta.... stuff like that. I did it because I knew I wouldnt be eating things like this for months. 

I would also allow myself to have a Skinny Cow ice cream once a week. Rewarding myself like that worked for me, and now, 3 weeks after surgery, I struggle a little, but I realize I will be able to eat "real" food again soon... the first couple of months are pretty restrictive, but are SO worth it!! I have lost over 25 pounds since surgery 3 weeks ago, and even though most days are a struggle, I know it will all be worth it in the end! 

Just tell yourself you HAVE to do this. Its not an option anymore. 

Good Luck!

 When they told me I had to lose weight before surgery, I was like "If I COULD lose weight, why in the world would I want the surgery!?!?!?".   Thank goodness they didn't make me do a liquid diet or I may never have made it!  As it was, I just jumped in with both feet and followed the HELL out of the low carb/no sugar/high protein diet they gave me.  I lost the required weight in like 3 weeks!  I almost opted out of surgery because I thought "Maybe I CAN do this on my own."   In the end, I decided that my previous experience with "diets" had shown me that I did need the surgery and I am SO glad I did it.  It was much the same as the diet I eat now.. so it prepared me (as much as possible) for life after surgery.  I am grateful that they had me do it.. had I had the surgery without the change in eating habits, I would have lost my mind!  (Which isn't to say that I didn't have a day or so of food mourning afterward, but I am sure it would have been MUCH worse).  

Watch WLS journey videos for motivation or read the NSV posts in the forums.. or just look at before and after photos.  SO motivating!!  
  Good luck to you!!
