HELP PLEASE! I started on new meds and wanted to know if anyone has had any bad side effects with these

ok I need to see if anyone has had any bad effects with any of these. I was on 45 units of symlin 3 times a day, and 1 jaunvia a day, along with 25 units of lantas at night. I went to dr on wed, and my a1c is up to 10.5. It was 8.2 in feb. So now I am on a whole new set of meds. Byetta 5mg 2 a day, Janumet 1000mg 2 a day, Prandin 2mg 3 times a day. I still am on Lantas at night 25 units. On top of those, he also gave me Phenergan for nausea, and ambien cr for troubles sleeping. I started them today, but like any new meds, I like to know if any horrible side effects anyone has suffered. thanks for the info!!! and all the help.
