Does anyone else have these symptoms?

Last week something strange started to happen every time I ate. My heart rate goes up, I get slightly weak and dizzy, I’ll gradually get hot, and I get tired. When I don’t eat it just feel like I’m bloated, nauseous, and about to pass out. I have MS and from the literature that’s out there now my symptoms should be subsiding because of pregnancy. But that doesn’t mean that I won’t have a relapse during pregnancy. I see my neurologist in 2 weeks and more than likely he’s going to say it’s pregnancy related and I will follow up with my OB with this concern also. I’m keeping a food diary to see if it’s triggered but it’s not by any particular food. I can’t even walk around my house for a long period of time before feeling nauseous, dizzy, and weak. I’m 11 weeks I feel that stuff like this should be subsiding by now. Anyone have experience with this? If it keeps getting worse I’ll call my OB and leave a message to see what I else I can do other than lay in the bed all day! Thanks for reading this far, any advice is appreciated.
