I'm on day 3 of induction and have had a cracking headache since 2am this morning. I feel tired, disorientated and irritable.

I realise that this is the withdrawals that I've read about but what, if anything, can be done to alleviate these symptoms? How long should I expect them to last?

I'm in this till the end so I will just have to put up with this if there is no other option!
