For me, dumping can happen at any time.  It has happened hours after or very shortly after.  You said they are doing a sugar screen?  I think that is good as it could be a diabetic problem. 
I myself watch the amount of carbs I eat.  I don't eat any  really right now.  I am on a no sugar no flour food plan and only eat oatmeal in the AM as a grain.  No pasta or sweets for me.  Eventually I will get to up grade to some brown rice and baked potato for lunch for or dinner.  This has helped me immensely.

Don't take this as the word, but from what I've found, Dr. Rita is not doing the DS any longer.  I'm sure it's an "option" for her patients, but from my standpoint it looks like there is a huge amount of DS patients that have not been compliant with the post op requirements.   That's one thing I love about Dr. Rita.. she has no problem telling patients NO.  She really is our best ally when it comes to surgery.

Once I heard the rumor yesterday that she wasn't offering it, I wrote Susie an email asking if it was true and if so, why?  I sent it after hours, so maybe I'll hear back by monday or so. I'll let you know when she replies. I just find it so strange.

Hi Cee, thank you for getting back to me.  Yeah, so far I have not gotten to see much of her, the initial visit with her PA's I didnt get to speak with her but for a minute of two, but i totally understand she is very busy.  They told me everything I needed to know.  I just wanted to ask around and see what others thought of her and if their surgeries went well...

Now I notice you got the DS.  Do you know if she still offers that, or if she doesn't, why?  I just heard about DS recently and it was never really given to us as an option.  Some have said they think she stopped doing it, and I was just wondering if you had any insight on this...

Hi Prettysoon!  Thanx for the reponse!  I began my 6 month supervised diet in September.  I agree that Dr. Wells is a considerate and professional individual.  Also, Dr. Z seems pretty friendly and I don't doubt that he's an experienced surgeon.  However, I am very interested in hearing your experiences with Summa.  Good luck with your appointment next week.  Let me know how it goes.  By the way, what was your beginning weight?  Its very interesting that you lost that much weight in such a short time...CONGRATS!  Do you have any problem with excess skin?  Thanx again...take care!
