Hello! So today is my second day on the pre op diet. I'm supposed to have 5 to 6 protein shakes a day and that's it! The nutritionist said I may have non starchy vegies if I'm starving. Yesterday I did fine. Today however, has been a nightmare. I have had a headache all day (I kinda expected that), I've been dizzy, and threw up twice. I only had 3 shakes. I just ate half a cup of green beans. I hope it works! I just hate that I'm already having problems. I stil have 7 more days of this to go! Has anyone else been through something similar? I believe my blood sugar dropped. I'm feeling really discouraged. Any advice or encouragement is welcomed! Thanks!

Are you allowed to have broth? Sometimes the headaches are really the result of the sodium reduction and maybe some broth would get you through the feeling bad. Also, drink lots of water!

She didn't say broth. She said I could have that the day before surgery as I'll be on clear liquids then. She only said I could have the non starchy vegetables. Which I just thew up. I'm trying to drink water, but I've been throwing that up too. This is so upsetting

Are you also withdrawing from caffeine or artificial sweeteners? If so, the first three days are somewhat tough. I suggest you call the nutritionist back and ask if you can drink broth. I could/can handle broth even on days when the Protein shakes just make me want to gag. Also ask her if you can use other kinds of shakes and/or crystal light (for the artificial sweetener). I was also allowed Kelloggs K2O Protein drinks both pre and post op. I got really sick of sweet stuff really fast, which I think is one of the points of the liquid diet. It creates an aversion to sweets, IMO.

Some Protein Shakes are much better than others. Also, Protein shake has a lot of definitions, unless they are making you drink one particular kind. Do you have a Vitamin Shoppe nearby? If so, you can buy single protein shakes and try them to see if one or another is easier for you to drink.

Try heating or cooling the shake. Sometimes it's easier to eat if you can pretend it's hot chocolate or pudding. The texture change helps some people.

Click Espresso flavor (available through Amazon) is one of my favorites and I add it to decaf coffee. Walmart sells a couple of different brands of whey isolate protein that are decent. I don't have any here or I'd give you the brand names. Look in the HBA section near the pharmacy.

Good luck on your journey!!

Oh, and are your nerves just on edge? That might explain the vomiting. If so, diet or not, make yourself a nice cup of hot decaf tea and take a warm bath and relax. You will get through this and you will be FINE!! And, I mean that in both ways!

Thanks so much for your advice! I was only allowed to choose from 4 types of protein drinks. The one I chose is GNC 100% Whey because the other three you can only get online. I do not drink coffee or use artificial sweetners or anything. I've heard of people going through CARB withdraw, and that could be it, I just didn't expect the vomiting :/ I don't feel nervous or any of that. I'm hoping as you said, that the first three days are the worst. I am going to try mixing my protein drinks with water tomorrow to see if that helps. Also, if I don't feel better by Monday, I'll call the nutritionist back. Thanks again for your help and encouragement!

Oh and by the way, I don't have a problem getting the protein shakes down at all. It was later that the nautiousness hit. I actually haven't even been that hungry so far. I'm grateful for that.
