Another name for it is metoclopramide and it took me 6 months to go see my doctor because I was extremely tired and suffering mild depression. After a week of stopping I came back to normal. The drug worked great, I just took 10mg before going to bed and with 30mg of Zoton in the morning I was symptom free
I am now on an alternative but if you are interested in the reported side-effects, check out the UK yellow card database http://www.mhra.gov.uk/home/idcplg?IdcService=SS_GET_PAGE&nodeId=959 which is where doctors and patients report side-effects. You will need to look until the UK name for the drug.
In my experience the drug worked well, but unfortunately I just couldn't tolerate it. So I think its worth a try to see how you get on.
