Lol, I've had the same thing, reaction to nerves pending Uni.....I take Kalmz tablets (one with each meal) they're good coz herbal and don't make you too sleepy that you can't function in the day, but they do mellow you out, make you less nervy, hence I'm sleeping better now (sort of.) Also taking St John's wort for depression, but have to take these before bed coz they do knock me out a bit.....fatigue is listed as an uncommon side effect but coz I'm underweight it affects my body a bit more (according to the doc, anyway.)
