I know that the liquid diet is VERY hard. I am 16 days part op and have been on mushies for 2 days now.
It felt like I would never get to the 2 week mark but try really hard to sick with it. I'm not sure what specific liquids your allowed to have but I can tell you what helped me. I would mix up milk, a little ice, Protein mix (any flavor you like), & sf, ff pudding mix (flavor of your choice) with a little splenda. This have me a thicker liquid that was still on my dr list.
Just hang in there...what seems like an eternity now will be a distant memory before you know it. It is amazing how your brain plays tricks on you but you are strong and WILL make it through!!
