I have had chronic back pain for the last two years with nothing helping the pain long-term (nerve ablations, physical therapy, acupuncture, chiro, etc.) and started brewing in January of this year. Since then, I've find that drinking a few beers a night really helps to dampen the pain. Also, I feel a million times better putting delicious beer that I made into my body than narcotics, and feel like it's much less likely to form an addiction.
EDIT: I also had friends suggest smoking weed, and I love the smell of the stuff, but honestly I think brewing beer is much easier/cheaper/legal/readily available than getting a medical marijuana card and buying it from a dispensary, or buying from a friend. I also like the taste of beer much more than I like putting smoke in my lungs.
I would say I drink 2-4 pints pretty much every night that I'm at home without being too busy to drink. If I'm working on projects (like the water supply line that cracked in our front yard, for instance, or after-hours IT projects for my job) then I usually won't drink while I'm working, and depending on how late I'm up working on them if I have time for a pint before bed I'll usually have one while I decompress.
Like others, I really enjoy having a pint when I get home from work. I do feel bad that because of my back problems, my exercise level has decreased quite a bit, and my pants are fitting a bit snug... So I either need to drink less calories or suck it up and exercise with the pain.
