PLEASE HELP. 6 Months of anguish. Think its Giardia

Hi guys,

First off wanted to say thank you in advance for any help you can provide, been a long time lurker and learned a lot from this site.

 I went to mexico 6 months ago, have not been right since. About 10 days after, started pooping 5 times a day loose stools or diarrieha, yellow and floatiy, dont digest food, dont gain weight, i see little yellow spots in my stool, got the sulfur burps, always hungry, and i even felt something moving in my left intenstine when i get hungry.

Anyway, got a stool sample but was not told the correct directions. Now it has been 6 months of suffering, i poop 3-5 times a day, i always see yellow spots in it, it is always loose, cant gain weight, and beer/wine just makes me sick. Finally my psych of all people heard about it and gave me Flagyl, which i have been asking for.

However before i do that, i wanted to run my it by you guys and show you the pictures. Let me know what oyu think and if it may be anything other than Giardia, thank you all!!
