Any suggestions re "gas"..?!

Bloating and burping!

Just wondering if anyone else has experienced this. I'm in week 2 of 40 clicks in my 5 mg pen and so far good steady weight loss being down almost 7kg since commencing on a 2.5mg pen. But suddenly on Day 2 of that second week, I feel very mild nausea but huge "gas" especially burping and also f*rting! I've taken some deGas (simethicone) and also some prochlorperazide/Nausatil but not really doing the trick! I haven't let up on my new water intake habits nor changed my eating. Help!
