Hi mate,
What the tablets should make you do is feel " normal " again.
It can cause a bit of anxiety when it happens, as you become so used to being on your arse or wired, that when they start to work it almost feels that something is wrong due to you having forgotten what feeling " normal " is like.
My advice is to take the tablets religiously at the same time(s) every day, that way it becomes part of your daily routine and you won`t forget to take them. Plus they`ll work as they`re supposed to to due to the correct levels of meds always being in your body.
Once they start working, don`t be tempted to stop taking them, as you`re now " better " and don`t need to take them anymore. ( a lot do this ).
It`s the tablets that are making you feel better, so keep taking them.
They`re not an exact science, so you may need to change your dose ( up / down ) or even change them if they`re not working as they should.
You`re GP should be monitoring this and maintaining regular contact with you ?
Keep up the good work mate, it`s always great to read positive posts like yours.
