Kelly, go get checked for a sinus infection. Infection
of any kind messes with my MS symptoms BAD!
As far as moving up, I would wait till your fluxuating symptoms (perhaps due to your sinuses) are under control.
My only other concern is that I am just about at the point where I ALWAYS have to lower my LDN because the weather is changing (and I've been on it for years!). I picked late Sept to try to move up to 4.5 mg the first time (and I did it in .5mg increments, not 1.5mg all at once), but I couldn't do it then. I think I got up to 4.0 mg (not even 4.5mg) and I had to go back down again until my body adapted to the weather change about 3 weeks later. I think I was able to do in two quick .75mg jumps after that.
Another option would be to dump the contents of the 1.5 mg pills into 1.5 mg of distilled water. You can do this with say 10 pills (15.0 mg) in 15.0 mg of distilled water, then each night take 2 X 1.5mg, PLUS .5 mg of the liquid LDN for a few weeks.
The next two weeks you can make up 30 mg of liquid, and add 1.0 mg to your nightly dosage of 2 X 1.5mg of pills. This way you can move up in much smaller increments.
If you try that, just make sure to keep the liquid LDN in the fridge, mix it well before you take it . . . and be warned that the stuff tastes like

without any flavoring added (my pharmacy adds flavoring to my liquid LDN).
Some people START at 4.5mg though, so you might not have any issues either.
Cherie
