i do this all the time! i keep two journals, one in which i write rantings of my daily encounters, and one in which i break out whenever i am high and feel like writing. there is some really amazing stuff in there from my acid, 2cb, and hawaiin baby woodrose trips. as you can guess, the acid encounters are the best. i had a bad habit of writing off the page or writing a few words on one page but feeling like a wrote a thousand words crammed into a small space.
