go get yourself a pregnancy/breastfeeding drug book. theyre free or very cheap at pharmacies. asking advice on the net during pregnancy is, um, whats the word...sheesh cant think of it...tip of my tongue...coming...hhmmmm...STUPID!
ahem.
first look at the basics. diet, and sleep.
in regards to diet, look at how many carbs and how much protein/fat youre getting per serve, and at what time of day. low GI carbs increase blood glucose and make you feel more energetic. high GI carbs make you feel awesome for about 15 minutes and then your ass crashes. high fat/protein meals (especially large ones) will open blood vessels in teh gut, diverting a lot of blood/resources there, plus giving you a big insulin hit, and your energy tends to plummet and you rest your eyes while you watch tv
so check it out and see what the story is. not only do you need to think about meal timing and relative macronutrient proportions, look at total cals.
after that, make sure youre sleeping well - check out your sleep environment: are your sheets clean and comfy? are you used to the bed? are all the lights off? (including LED lights on alarm clocks/stereos) any loud noises at night that wake you? (cell phones all turned off? sleeping pills in the dogs bowl so that theyre all KO? windows shut to keep out road noise?) do you prepare for sleep properly? (reading a book/soft lights/soft music/meditation/shower) are you exercising, and therefore tired enough for good sleep?
if none of that works, consider cocaine
thatll be five bucks thanks
