Suggest Remedy For Nausea After Eating

I am a 39 yr old female and have been expierencing nausea after eating for over 2 years now. It is not constant but happens at least for two weeks out of each month. Immediately after eating I feel extremely nauseous and my mouth will start watering really bad, sometimes I throw up but most of the time I try to hold it back because I hate throwing up. I have noticed that diet sodas will trigger nausea if I have them with a meal and it is hit or miss with other foods. I had a hysterectomy in Nov 09 and thought that may help because before that I noticed it would always get worse around ovulation but it still hits me every month just like before. Could this be hormonal because I just had a CT scan done of my abdomen with normal results although I am getting a second opinion because I have lower back pain and abdomen pain on the right side. Any advice of help you can give me is greatly appreciated because I feel like I keep going down dead ends and the Dr s dont take my symptoms seriously
