The last 2 days have being strange for me as I am doing everything the same , the last 2 night I think my stomach is going to fall out, between gurgling and snarling I think there is something in there , I'm drinking 3 1/2 litres of water aday plus 3 mugs of coffee and my 3 shakes , it's very loud and embarrassing , and my sleep pattern has totally changed ,not going to sleep until 3 am , all advice appreciated
