I know the body fluctuates 1 to 2 kg daily . So hopefully your weight might pick up by next weekend.
i was always told to NOT weigh every day - once a week is plenty often enough.
Ah, I guessed 1-2kg/d would be normal. And normally I've before and since fibro usually weighed myself about once a month, incl. when amitriptyline put on +6kg, which took 2 years to get off again.
Now, tho, I'm going for all details, trying to get a feel for
my exact bandwidth, times of the day, weight of clothes, other influences, like drinking/peeing/taking GABA, eating.
From 80-82 down to 75 in a short time isn't good, but down to 73-74kg is worse.
If at that speed I were down to 72 sometime this week I'd want to know immediately.
Checking any levels, like temperature, blood pressure, pulse, pee amounts etc. always gives me food for thought. Also looking things up, like what is the correct way to measure things.
Docs are no help at all with details or these measurements. In the same way my GP does it, the practice assistant measured my blood pressure on Wednesday directly after after I'd heaved myself up from my seat in the waiting room, trundled down the corridor still struggling my stiffness from sitting and dropped myself in the seat. 150/90 I said. Yep, exactly 150/90 she said. I put it down to "excitement" cos it's easier and less reproachful - which of course isn't the full story: all the experts say you need to measure blood pressure after at least 5 minutes of rest and not talking. There are about 5 further "rules" to heed. My wife says "they're silly", because she doesn't know them. For instance taking blood pressure 3 times and taking the middle value. Personally, I've found taking it about 8x will give me an impression from where to where it goes, how much it fluctuates etc.
Another example: In a cardio ward they made me wait for 4 hours - and it would have been more. It was because my pulse was too fast for a certain exam, but they didn't tell me the whole time, so while I was waiting I was doing stretches and exercises cos I can't sit that long of course which brought my pulse up of course. Once they'd told me what the problem was, I said: Ah, I can influence my pulse, no problem, so they sat me down, and I said give me 5 to 10 minutes, and I did autogenics or NSDR/Yoga Nidra and voilà, pulse low enough for the exam. (I once scared a nurse in a wake-up room after colonoscopy. I could see my pulse levels, and that it was quite a bit under 60, so I reduced it to 50 and the gadget started putting out an alarm. She got a bit angry at me, but I didn't take that seriously, because after all I didn't know...)
When I take my bp/pulse, I do it "properly", which for me is 8x, resting, forearm in heart height and keeping note of the progression, like 170-140/100-90, which considering the T4 and nicotinic acid, and my hyperactive body and mind - is OK, compared to people taking less and being less active.
Problem with body weight is I have no idea yet how it works generally or how it works in my case at the moment, I'm just pretty sure it used to be pretty stable, from 75kg to 78kg for a long time when I was fit, +3kg for clothes, then 85 from amitritptyline (in my case hardly from becoming sedentary thru fibro), then after 2y 80, and now 73(-75). I can't see how it can get higher at the moment, because my appetite has been a bit better about 3 weeks now, with cheating, by eating things I shouldn't be, like lots of dark chocolate, so there's no more slack, just more cheating, like increasing "healthy" marge a lot.
For my histaminey sinus burning today after a 30' talk, adding even more GABA is helping (4g is breaking all records), but altogether it's knocked me head over heels, cried a lot, can hardly move, only slowly think.... My probably last talk ever, but I think my best, from what people said - that's the way to go... Every time I play music publically, I know (and say to some) it might well be the last time. But I still try to find ways to do everything slower, simplifying and learning to lick and bandage the wounds better (e.g. using GABA, like said).
Drinking more, quite a bit above the 3L/100oz. mark, does seem better for my evening headache. There must be / are quite a few downsides to drinking so much, e.g. for appetite/eating/weight, bladder, and I
would like to know any cause, incl. if it's due to any supps or their combinations.
, the stuff I moved around all day Monday I've still got sore muscles in my legs from.
So if anyone asks how come I weigh much less than when I was extremely active, we'll just whistle harder and louder... 
. Supps and eating in the garden now, bit late, but I'll concentrate on that rather than being creative. Night sweats better now not using hot water bottle for the cough.
