Not that i know of!!! never happened to me...id speak to your dr or pharmacist if i were you!!! good luck! caz xx ps you have'nt justdramatically dropped your caffine intake by any chance or upped it???
are you drinking enough water and caz is right too if you usually have caffine then dont stop now , take it easy the first few days then ketosis will kick in and you will be full of energy xx
I'd agree, it sounds abit like caffeine withdrawal. If not, maybe drink more water and really reduce what you're doing, rest lots and pamper yourself a bit.
It's not good for the first 5 days, but you'll feel great after that.
