I need advice/help!

OK, so I figured that since only women read these, I need HELP! I really am trying to nurse Jackson, I triedwith Kiersi but didn't produce much and am having the same problem with this one. I have tried herbs, a mothers milk tea, the prescription but nothing seems to really help. I just may not be the nursing type but I really really want to, and fomula is just expensive and I don't want to have to use it, he likes it which is awesome but I want to nurse too! So... if any of you have any thoughts on this I would love some advice.
ALSO, lately I have been getting bloked ducts, which hurt like the DICKENS! I get them on one side only and it takes everything out of me. I've tried everything I can think of. I just don't think its normal for them to come back on the same side every stinkin time! anyway it hurts and I don't know what to do. All ofthis really makes me want to stop nursing him but I am trying my best to keep it up cause I know its good for him!
Anyway, kinda a dumb post but I figured different people may have gone through the same thing and would have some help for me cause I REALLY need it!
