Lactaid and viral infection

Recently, I had an experience very similar to pocoloco's experience with Lactaid. The main difference is that pocoloco experience seems to have wained within hours, mine were much more severe and lasted for days.

On a Monday, I took some Lactaid before eating a salad, that had perhaps 2 tablespoons of Ranch dressing. The next morning I awoke with very painful stomach pains. Like pocoloco, I feel I have a high threshold for pain, but throughout the day, I was unable to concentrate on my work because the pain was so severe. I went to my doctor the following day as I had not made a connection between my pains and Lactaid. The doctor had bloodwork done and a sonogram performed. She thought that my pain may have been the result od some gallbladder trouble or a viral infection. She prescribed a strong antibiotic, pain medicine and ulcer medicine to attack it from multiple angles as I am a healthy 32 yr old.

Over the next several days, I was feeling better, but still in discomfort. On that Friday, I took a Lactaid pill with a bowl of cereal for dinner around 7-8 pm. By 11 pm I was vomiting violently and had extreme abdominal pain. Again, because I had feeling better, I thought that perhaps I had a bad reaction to the combination of antibiotics and pain medicine. I vomited over a period of 4 hours, and like pocoloco, was expelling yellow/green liquid (bile?) near the end of the experience (3-4 am).

Between Saturday and Tuesday, I was still in discomfort, but was 90% better by Tuesday. I decided on Mexican food for dinner. I took a Lactaid pill and had some Queso with chips for an appetizer. By 11 pm, I was vomiting more violently than the first time and had a strong bitter taste associated. I finished vomiting around 5 am this time and the following day was still nauseated and in very strong discomfort from stomach pains. This was all it took to finally connect the dots and realize that the effects were the result of Lactaid, not a viral infection or stomach flu.

I would say my experience was very similar to pocoloco's, except that my stomach pains lasted over several days and my vomiting was over 4-5 hours as opposed to his 1-2 hour experiences.
