How can I stop shaking during an anxiety attack?

I have had multiple times in my life where I would wake up in the middle of the night with the most suffocating and terrible globus sensation in my throat choking me. When I have the Globus sensation I feel like I am going to throw up and I have a bad fear of throwing up. I also have stomach pains and entire full-body shakes. The only way I can stop these shakes is by waiting it out which can lead to either 30 minutes to a few hours. I usually can then go to bed afterward but I am so sore and it tanks my mental health and energy for a day or two. Breathing exercises don't do shit and they only make me feel like I am suffocating a little more, I usually put my legs up and lay on the floor but sometimes that doesn't help, I try to distract myself or self talk but it doesn't help most of the time. My biggest fear is throwing up and I have slightly gotten over the fear of it but it's still not something I want to do because I find it so horrid. My anxiety has been worse. I am not currently on any meds because my last ones disagreed with me and had bad side effects. I want to get some good sleep tonight as well but I am scared that I will be thrown into this situation again tonight. The reason why I am making this tonight is because I was stupid and decided to have some ice cream that I like and stupidly forgot that it doesn't agree with my stomach. I have now decided I am giving up that icecream forever because it's not worth the pain and mental energy
