Desperately slow Mac since Yosemite!

Since upgrading to Yosemite recently, my MacBook Pro is very slow to respond to anything. Programs take ages to launch, and trying to open Mail and Safari is even worse. Once Safari has eventually loaded the homepage, it is slightly better but I dread closing it as I have to go through the same procedure the next time.

I looked at Activity Monitor, and in particular the Memory tab, and it says I have 4.00GB Physical Memory but it has used 3.98GB! However, I don't know where to look to see what big players are using it. Neither did I install anything new and it was working fine before.

Can anyone help?

I realise my problem is shared by many others and maybe folks are weary of explaining the same advice. I tried to see if there was anything on the Apple Support discussions and, of course, there are quite a few topics on the same theme. Strangely, when I tried to login to post a question, I seem to be barred from seeing any of the discussion, with the links all being 'out of date.' I found the discussions again on my iPad, tried to login again and was barred again! So clearly Apple are not wanting anyone posting more comments about how awful this update is.

One possible way of fixing it was to do a reinstall of Yosemite but I can't find how to do this. Can anyone explain how this is done?

Thanks.
