Hi ghost_whistler, I haven't been around for a while but have just had a very quick read of your posts. Sorry if I repeat or even contradict any advice you've already been given as I have to admit I haven't read the whole thread.
I was diagnosed with RH around 18 months ago and can say I completely understand where you're at. I was so confused and scared! My GP knows nothing about the condition and like yours, repeatedly ruled out diabetes and pretty much made me feel like it was all caused by anxiety. Anyway, long story short.....fast forward those 18 months I am now feeling pretty good! I can't remember the last proper hypo and when I go "low" (mid - low 4's for me) I don't have the real crashing, sweating, anxious feelings I had before.
Like you, the whole being in ketosis thing didn't (and still doesn't) appeal to me. If I start producing ketones in any amount I feel simply rotten and can barely function. Now I know that I might get past this faze with a little perseverance but I have two small children who can't look after themselves while Mummy sorts herself out! Again, long story short, I now do very nicely eating around 100-130g of carefully selected carbs per day. My fat intake has risen to approx 90g per day and protein I guess around 70-80g. These are very approx of course and vary from day to day. My body seems to work better if I include a small amount of carbs with each meal. Maybe yours does too?
My Endo also recommended porridge for breakfast but it doesn't work for me. It gives me a fast spike up to circa 9 and then an equally fast drop to 5's. It seems to keep me steady once the initial drop is out of the way but I feel starving within an hour of eating it not to mention a little anxious due to the rapid bg changes!
My typical day is:
Breakfast - Greek yogurt with a small amount of no added sugar muesli (dried fruit removed), a few blueberries, raspberries, almonds and a sprinkle of cinnamon with a with coffee.
Morning snack if I need it (which more often than not I don't now) is a few dry roasted peanuts, a spoon of peanut butter or a very small apple.
Lunch - salad with fish or meat and a thin slice of low GI bread or an omelette with toast, or eggs (anyway you like) on one slice of low GI toast. You get the idea!
Dinner - salad, roast dinner (couple of roast potatoes, roast celeriac is good alternative to potatoes and chips etc). I can include a small amount (no more than 100g cooked weight) of wholegrain rice or pasta with something homemade so I can control the ingredients. I can also tolerate a very small jacket potato (absolute maximum 150g uncooked weight) with cheese, coleslaw and salad etc. I even eat one slice of pizza with salad and make my own version of pizza using a Lidl high protein roll.
We're all different and have varying activity levels and metabolisms etc so what works for me might not work for you. I only got to this stage through A LOT of trial and error and testing. It took months for me to start to feel good again and regain my lost confidence. I'm not going to lie, it's still hard especially when away from home but please keep going as life can and will be good again.
I never thought I would be where I am today and although I hate RH intensely, I do enjoy life again and realise there are worse things to have. It's become more of a way of life.
Anxiety was my biggest nemesis and it still is. Once I got my stress and anxiety levels in control (which is far easier said than done), I found my RH easier to control. Even now, if I'm stressed or worried about anything it messes with my levels and makes control much more difficult.
I hope I haven't just made you even more confused. I just wanted to show you that there may be another way of tackling the problem which may work for you.
The guys on this forum are awesome by the way! I never would have got through the first year without their help and support. Just knowing that you're not alone is invaluable, so keep coming back and ask away. There is always someone here for you.
All the best.
