I started LSD few days ago and that is when the tiredness really set in....I am wondering if the lack of carbs is exhausting me but I dont see anybody else here complaining about that...it seems everybody gets lots of energy from the diet so maybe I am doing something wrong.

You are doing NOTHING wrong!
It is most likely that you are suffering from the sudden withdrawal of a 'easy' energy source for your metabolism and your body is not yet fully keyed up to switching on more ketotic metabolic energy pathways.
Maybe try to include some fruit / fruit juice several times a day in the early days so you have simple sugars that are readily digested higher up in the digestive tract so that You and not the Klebs in your large intestine can utilise them for energy.
There are PLENTY of folks who complain about the lack of energy on the LSD / NSD in the early days.
Hang in there - it *does* get better with time.....
You really need to talk to your rheumatologist ASAP about a (hopefully) short term management plan for pre-conception and pregnancy. It might include COX-2 type anti-inflammatories - safest on the GI tract and maybe sdome purely analgesic med too so you can function with less pain.

- this is no easy road, that's for sure! I actually found that the natural steroids made by the placenta were a real life saver during my pregnancies!
