Day 14 bupropion xl help!

I’m on day 14 of taking Wellbutrin for depression/adhd so far I’ve had no side effects (until today) and have noticed no change which is to be expected I’m on 150mg

Today at about 11am while I was at work I was partially bent over and when I stood up straight I got hot and felt like I was going to fall over and maybe faint. That has not gone away it’s 9:23pm as I write this. I ended up leaving work early and going to urgent care they were not helpful at all my BP was 117/93 they ran a bunch of tests and said I was fine and sent me on my way despite the fact I was still dizzy/vertigo and tired I just felt really really out of it. I ended up calling out of work tomorrow when I got home i managed to get some chicken noodle soup down and then I took a nap for an hour woke up for maybe 20 min and fell back asleep and woke up two hours later heavy and drenched in sweat. It’s not as bad right now I’m just really unsteady/ unbalanced but earlier anytime I moved at all I could feel the blood rushing to my head and I’d get really dizzy/ kinda lightheaded.

Anyway is this normal for this to be happening now? Will this go away? The only thing I can think of is that it’s the Wellbutrin but I can’t be like this at work, I’m a dog groomer I have to be able to walk around and stand and bend over without almost falling over. I’m supposed to work on Saturday too I really don’t want to call out of work again but man I don’t know what to do. I’ve messaged my psych she thinks it’s lack of food or water and wants me to keep going with the medication but I know this isn’t a lack of food/ water issue. I do vape nicotine I want to quit of course but I know that can also raise BP. I just don’t know why I’d be getting side effects now after taking it for two weeks

The urgent care I went to did bloodwork, urinalysis, and a EKG and took my BP and HR while laying down sitting up and standing and they said everything looked great and I’m “fine” 🙄 and told me to eat food and drink water but didn’t help figure out why the hell this is happening in the first place.

I also usually skip breakfast so that’s not new and I was drinking a redbull this morning but stopped as soon as i started to feel bad I had maybe 1/4-1/3 of it
