I am a newbie and need info, Please?

First I want to say how wonderful it is to come to this site. Everyone seems so caring and with the frame of mind I am in right now, I need that!

2 years ago, I had to be on different Antibiotics all in a row, first because of a spider bite then an abcess tooth from the spider bite, then bronchitis. To make a long story short, I had allergic reaction to Antibiotics which caused a false gallbladder problem.
Upper Gi and Ultra sound showed everything was clear.

Finally the pain went away after all Antibiotics were out of my system..well now last month (Feb) after eating bad, bad food..(barbecue Pork, homemade chicken pot pie with heavy cream, ice cream every night) I had the same pain again.

It happened 5 times in a 2 week span. I am having an allergic reaction again and the pain didn't start til after the allergic reaction started. I have been so afraid to eat. I am only eating broiled or baked fish or chicken, vegies (almost raw), apple sauce and sweet potatos, whole wheat bread..well you get the picture.

I was told by a friend to use 3 tablespoons of Olive oil and the juice of a fresh lemon in the morning and at evening for 3 days. Will this help? Does it really help? Do I need to eat lightly when I do this? Do I lay on my right side, left side? on my back? For how long after I drink this? Will this clean me out?

Please tell me how to do this. I am slightly scared. I am not having any problem right now other than maybe a little full feeling.

Thank you everyone for any info you can give me.
