I know that lack of exercise is one of the main routes to feeling terrible.
But going running or cycling (even on the exercise bike) isn't particularly appealing with all-day nausea and heartburn, belting headache, and being incredibly tired. I'm only 7 weeks and I am already unfit and fat and can't fit into clothes properly. I'm walking about 7km a day, down & up a 200m-elevation hill and even that is feeling like way too much.
Any suggestions? Does it ever get any better or do I need to buy bigger jeans and wait until the kid's at school before i get fit again...?
