Are you fasting (as in no food) or are you just eating less on your “fast days”? If eating try eating your meal late in the evening. Im assuming you are no longer overweight? Frequent urination is a indication that you are running on ketones. Urination is a means of keeping you from going into keto acidosis.

Do you take any supplements? I’ve heard that a magnesium supplement before bed can help with sleep, I’ve never tried it personally though.

yes. Really struggling to get to sleep and last night woke up w leg cramps. Am going to try magnesium supplement today. I suspect its because I’m not crashing for sugar/carbs. I don’t feel tired despite crappy sleep……..

Also heard about melatonin, never tried it personally but for some acquaintances it does work. The lower dose, the better, I heard.

OP, I’m not sure if you drink, but I’ve found that saving a few calories for a glass of wine in the evenings has helped me sleep quite well on fasting days. Dry, red wines have especially been useful in helping me drift off. I’d stay away from the sweeter stuff (i.e. moscatos, sweet reds, viogniers), as I’ve found they make me feel hungry or snacky. Could just be me, though!

I’ve found since my earlier post that eating habit has changed, eat very little until a main meal after 6pm, but last thing have a glass of milk, seems to help me.

@mukica – Different bodies certainly process things differently. For me (as well as my husband), a small glass of wine has helped considerably with falling asleep. If it doesn’t work for you, then certainly give melatonin a try!

i’ve stopped and restarted 5:2 because of this, I am wide awake and sleep so light on fast days i’ve tried everything including magnesium and valerian root – it takes the edge off but still don’t sleep!
