I was prescribed naproxen yesterday (2x500mg a day) by our local MIU for a sprained ankle which has progressively been getting worse for about 10 days. Anyway I have taken 2 tablets (12hrs apart) and I feel completely wiped out today and constantly hungry. I slept well last night and have eaten quite a lot but all I want to do is have tea and crawl into bed. Does anyone think this is related to the naproxen or am I going down with something else??
