Blood pressure/cold extremities before feed window

I am just ramping up with IF, doing 12:12. Eating 10 am to 10 pm (actually 9 pm, giving some time for digestion). Working to ultimately do 15:9. My issue is I wake up around 5:30 am and by 10 am when I'm allowed to eat, I start to feel cold, hands and feet and face get very cold, to the point my fingernails start turning blue. I have had eating disorder issues in the past amd I'm familiar with this degree of hunger and this state overall. I am in my second week now and I haven thinking my body will adjust. I would shift my hours to eat earlier in the morning since it's much much easier for me to not eat at night but since I work out in the evenings, I need to eat or I'll feel dizzy. Has anyone encountered similar issues? Did you get used to it? Any suggestions? Advice? Thaaaank. via /r/intermittentfasting https://ift.tt/2M4H4gs https://ift.tt/eA8V8J
