I might have this as well, seems that I am very sensitive to to any form of sugar, even fruits.
I def. need to talk with some speacialist about this. I am pretty immune to POIS relief methods which helped to other members, but cutting sugars, made POIS a bit and whole life a bit easier., since ven when nonin POIS I relised that foods rich in suger, no to mention white sugar make my mind overstimulated, makes me feel burning in cheast, tinitus etc.. When I quit sugars my concentration, motivation, patience, ability to feel and exiriance emtiotions and well as general well being immproved a lot. So,
I am starting to belive that some sugar related intolerance might be cause for my POIS, and also another promblem which I have, and that is depersinalisation, low energy, headache, anxious mood after nap, too much sleep, or sleepinin wrong time. Seems that some other memebers also expirience this.
