I became extremely fatigued yesterday around 8AM, felt like I had sleep aides in my system (I didn t take any), then around 4PM my mouth got real dry, and stayed dry all night. Around 6PM i started getting chills (like tingling) in my shoulders and head ... Today, still tired but not as bad, dry mouth is still there, reduced a little, and no more tingling. I do feel spacey today... What s going on?
