Skewed Instincts

My appetite really varies. 
Sometimes I feel like I could eat nonstop, but the majority of the time, if I am busy, I will go an entire day without eating and not even notice. 

On the flip side, if I am particularly hungry or abnormally hungry, my first instinct is NOT to eat. My first instinct is to check and see if I am due for my Methotrexate injection. 

MTX curbs my appetite... So if I am all-of-a-sudden famished, I usually know that the injection is either due or overdue. 

Weird right?
