Glad to hear it's getting better. Time seems to make beer better. I bet the last bottle will be amazing.
I'm not a huge fan of kits. I'd suggest get some DME (diastatic malt extract) and make your own instead of using a kit. 6 lbs of DME, some appropriate hops (suggested by the good folks on the forum) and a yeast you like and you've got your very own recipe for making something just as good as a kit but it's all yours. Or, use a kit. But either way brew again...soon! You'll find you are out of beer faster than you could ever imagine.
For me, the advice on fermentation temps that you've already gotten was by far the best advice I received. Makes a tremendous difference in the taste of the beer. Plus, as you get used to hoppier, craft brew style beers I am willing to bet what you find bitter now is going to seem sort of tame in 6 months. Experiment, experience and learn from everything you do. Find something you like and do it again and again until you can do it in your sleep and then you can make subtle changes that make it even better. Spend time on the forum, ask for advice, listen to Canadians
, make lots of beer.
By the way, you may hold the record for the longest non -BFI post ever. Not sure what I mean, hang around you'll find out.
