I'm tempted to try 4.5 mg. but I still have this dizziness/vertigo going on. I'm not sure if it's a remnant of my sinus troubles or possibly just an MS symptom deciding to make an appearance.

My MS - as a rule - shows itself every year around this time (October). So....I tend to watch for things like dizziness, numbness, etc. to appear around this time of year. I'm fine as long as I'm sitting still but any sudden movement or trying to look out the window in a moving car.....no, no, no.....not a good idea!

I hesitate to bump up my dose because how will I know if I'm truly not tolerating it or if it's just my sx flaring up right now.
