You may already be doing some of this, and some might seem like common sense, but here's my advice. Rest as much as you can. Try to avoid standing for long periods of time or doing any kind of activity that gets your heart pumping faster. Take a relaxing bath (not too hot) with lavender or gardenia scented bath salts EVERY night (or day, whichever you prefer) and try to soak for at least half an hour. Drink chamomile tea and read a good book while you're snuggled under a fuzzy blanket. Make your partner or a good friend give you a massage as often as possible (one a day would be best, even if it's just a hand massage... it'll help keep you relaxed). Have as many orgasms as you can! Stay away from caffeine, drink lots of water, and rest, rest, rest. Try to nap for an hour or more every day. Also, try some breathing exercises or meditations. An easy one is to sit cross-legged with your back flat against a solid surface, place your hands on your belly, close your eyes, and concentrate on your breathing as you breathe in and out for a count of 4 heartbeats. And if all else fails, go to a pet store and play with the puppies and kitties. The less stress you have in your life, the better, so do things that make you happy!
