Recommend any vitamins for switch shift?

Hey everyone. Unfortunately, I have a switch shift coming up and overtime I take them I get tremors and other issues. Doctor says it's most likely because I'm not getting enough vitamins or something along those lines despite eating well.

Are there any vitamins you can recommend to help relieve the fatigue and effects of working a switch shift? I'm already using D3 and my natural B12 is at 200 without a supplement so I was told to take those as well. Any other suggestions to help with fatigue in switching from night walker to day walker.
