I am experiencing the same problems and have been since about 26 weeks.

I'm so irritable and uncomfortable by around 1/2pm i just want to go home! So i have a few times. I only work 4 full days but even this is a struggle. Hoping to drop to about 2 short days from 36wks until about 38wks as this is when the office shuts down for christmas and then i won't have to come back (for a while anyway!).

I think it's just something we have to endure. I have kept myself going until now by telling myself i need to keep earning money to put towards the 'baby stuff' layby but we just picked that all up on the weekend so now i'll have to find something else to keep me motivated otherwise i'll end up walking out of here!

What we go through for our little ones, hey!
