Welp this is simple. I'm on a medication and one of it's side effects is the sudden contraction of muscles. I don't mind twitching every now and then since I twitch enough as it is, but goodness my face and fingers have been twitching nonstop. Seriously I miss the migraines, the insomnia, the lack of appetite, irritable stomach, mood swings, etc. I'd love to have all that poo back just to get rid of the incessant twitching.
