I was just coming to respond to sumi, also. Spironolactone is a blood pressure drug, and statins (as I'm sure you already know, since you're taking one) are for cholesterol. Is it possible your doctor prescribed spironolactone and didn't tell you? (That's seriously not as implausible as it sounds.) But yeah -- taking a BP med when you don't need it is a recipe for passing out.
ION, I actually slept the whole night last night without taking an Ambien. This is probably the first night in maybe 10-11 months that that's happened. I started taking Wellbutrin about a year ago, so the insomnia tracks. (Plus the Year Of Many Loved Ones Dying As Well As Other Serious Shit started about a year ago. Stress + Wellbutrin = no sleep ever again without Ambien.)
My doctor, who I otherwise worship (as I believe I've mentioned a billion times) doesn't like to medicate insomnia with actual insomnia drugs on a nightly basis, because of developing dependence, etc. And while I can see that POV, I think the effects of chronic insomnia are worse than dependence on a drug that lets one sleep. His *suggested* alternative is to prescribe Remeron, b/c it's sedating. But, WTF? I went OFF Wellbutrin in May; I don't want to go on another antidepressant.
So he grudgingly refilled my Ambien for 1 month. At the beginning of July, I called his office for a refill. He was on vacation, so one of the other doctors refilled it for 3 months (I didn't ask for 3 months; I just hoped for another month). I almost wept with relief.
Anyway, I've been TRYING to get to sleep without it, assuming that sooner or later all the neurotransmitters that the Wellbutrin fucked with would calm their asses down and let me sleep. No dice. I've tried valerian root, I've tried melatonin, I've tried benadryl, and I've tried a combination of all 3. No dice.
Last night I had a small adult beverage (a wee bit -- seriously -- of Crown Royal and ginger beer, with dinner). About 3 hours later I took valerian and melatonin. I fell asleep while Tim was talking to me (I was lying down watching him try to pack a bag). I woke up a couple of hours later and thought, oh my god, I fell asleep without Ambien! And then I thought, well, I probably won't be able to fall BACK asleep now. I fell back asleep, until 7:30.
I might not be able to repeat it, but it was a fucking miracle, I tell you what.
