I am 35 and have had bulimia for 20 years. For the last 5 days I have been binge and purge free and eating proper meals. However, I was fine on days 1-3 but on days 4 and 5, I have experienced cold sweats (and sweaty palms), palpatations and a general feeling of weakness/tiredness. I used to binge on a lot of high sugar things, but since I started recovery I cut out all sugary things like sweets and cakes etc. Could this be low blood sugar related? I had a yogurt but it didn t make much difference. I have always had anxiety/panic attacks and whatever are causing these new things are setting off anxiety and panic and making things worse.
