The longest day in lab ever. I felt so tired. Probably failed another test. Grabbed a 15 min lunch. Plunged into an 8 hour long lab session. Ended up losing one reaction sample. Did lab from sun-up to sun-down, from rainy weather to sunny weather and back to rainy weather. Felt so fidgety, so restless, so flustered throughout the lab. Did plenty of wrong calculations. Maths was not on my mind. Fingers were trembling non-stop. Is that an effect of antibiotics? Had headache and tired squashy eyes that were ready to close any minute. The longest lab session ever. Ever single reaction took forever to complete. And with that many mistakes, I have no idea what my report will look like.
