Anyone sometimes feel like a heavy feeling in their head? Like there's a weight in it and you feel like you just wanna lay down. It's hard to explain but it comes and goes and I hate it!
Also get a super tired feeling too
I get that sometimes and don't worry its normal 
my head feels heavy almost all day. If your worried its something wrong with you see a doctor for a physical. If all comes back well its anxiety. When your stressed a hormone called cortisol is released. The is one of the worst hormones you can experience! It can make you feel ways you never have before. I personally wouldn't worry, stay strong!
I woke up feeling like that like my head is very heavy and I know I'm in on antibiotics for sinus so I don't know that could be causing it
