I am in my 7th year of remission from OC...
Right now my income is limited...and l am surviving on a very tight budget.
My current diet is 80% liquid.
Most of the available supplements such as Boost & Ensure are life savers..but they can be expensive...especially when you need to drink 6 or more bottle a day.
I have found that adding a can or two of evaporated milk daily is a fairly inexpensive way of adding calories.
A regular can ( 12 oz) costs about $1.30....much cheaper if you buy the store brand from Walmart.
I also add condenced milk to my coffee, shakes and smoothies for extra calories.
Granted, Boost & Ensure are more nutritious with more protein....but right now it's more important for me to retain weight and keep up stamina ..

Good luck...

Happy 4th to all members.
