Tomorrow I am writing five hours of law exam. It's past midnight, I need to get up at seven. I took 50 mg of Promethazine and I am further from sleep than ever. I feel so sped up and I feel like I could be enjoying it if it weren't just SO much and if I didn't need to write that exam. How the hell can my mood change from completely normal on Monday to feeling completely high without taking any drugs within three days. I am still overwhelmed by this. Surprises me every time. Any sleeping tips? Had a warm tea just now, cuddled up in bed watching a movie, waiting for the pills to hit, but they should long since have done so.
