Dizziness?

Hello, started GLP-1 on January 1st (wegovy) and made the switch to tirzepatide a few months ago. I’m down 20 pounds or so, but have stalled a bit. I started 75 units on Friday and every day since I have experienced dizziness. The worst of it is getting out of the bed in the mornings, like almost to the point of falling down. First half of the day I feel a little bit of lightheadedness, but second half of the day is almost all gone. Anyone else experience this? Will it go away?

I am making sure to drink about a liter of water within an hour of waking up and seems to help a little…it’s a lot, I know, but I read the dehydration could be a cause? I do drink water all day though.
