Starting my pre-op shakes tomorrow, advice please

Well i'm going to try my best. I got a last start this morning slept in since the kids were out of school, but so far i've done one shake and working on my first 22 oz of crystal lite, almost done with that. I think starting tomorrow. I'll get up at my usual 6, have a shake then about an hour later drink 22 oz of Crystal lite, then at lunch, i 'll have another round. then for dinner i'll do another round. and if i can make it with one before bed i will. Gosh, I hope this works out.

How are you making it?  I swear, pre-op diet was harder to me than post-op diet!

I'm doing good, I'm not craving food anymore, except late at night, so I just take an Ambien and go to bed, lol. Yesterday and today I haven't had all my shakes, yesterday only 2 and today acutally I haven't had anything, no shakes or anything to drink. I woke up not feeling well and tried to drink a shake and threw up. My daughter came home yesterday w/ a stomach virus, but she is fine today. Do you think not drinking them the past 2 days is going to hurt me and my surgery date? I'm going to try and get my 2 quarts of fluids in tonight and just start my shakes by tomorrow. Thanks for checking on me.
