First thing that you can do is breathe. Most likely none of the things that you have read are going to happen. Actually, the first dose is where you usually experience the worse side effects. Each week gets easier and by the 3rd or 4th week it is like any other med. On these low doses you don't lose hair, few people vomit although some have upset stomachs the first couple of weeks. If you continue to have stomach problems they will usually change you to the injections instead of the pills and that fixes that issue.
No need to panic. This isn't the dose they use for cancer and that is the dose you were reading the side effects about.
