Your baby wakes at night because he is 9 weeks old, not because you are not producing much in the evenings.
"....bad patch with cold that made his latch funny and although it works fine and didn't hurt(he gained a pound in last 10 days) BF counsellor this morning tried with me for half hour to improve it".....er, not sure where the problem is, if it works ok and doesn't hurt, and your baby is thriving so well
"DH wont help with anything"
Not fair. There is loads he could do. If you swapped to formula, you'd have more work with baby care (buying formula, preparing bottles, washing bottles).
You do deserve some time off - but formula could make it less likely than even now
Sudden stopping of bf is really not a good idea, believe me....and you don't sound as if this is what you want to do, you just want a bit of your life back and to gain more confidence in bf.
Please post more with more details if you can.
