Toxic stomach gas

Please anybody give me some hints about follwing:
I am treating candida now for 1 month, and I am having so many problems with an embarassing topic: stomach gas. - It´s not just that, but it smell like toxic or death - like s.th. is really wrong in my stomach.
I chew a lot, cook almost everything until it is very soft and easy to digest. I follow the diet very precise. For medicine I take acidophilus in the morning (1), Caprylic Acid (1) for breakfast & dinner, and an hour before or after breakfast and dinner Cytrus extract. I drink tons of water, since otherwise I get major headaches. So, I don´t know what I am doing wrong!?!?!
It is driving me insane, since I don´t dare to sleep next to my boyfriend anymore - I would be too embarassed (to tell him or if he noticed). This problem makes me really desperate, cannot sleep.
I´d be happy for any kind of suggestions, hints, shared experiences or whatsoever.
