Do you have any signs of an infections? Have you mentioned this to your doctor?
There are a couple things you can try, first stop drinking after 6 pm, do not drink any caffeine as it can aggravate your bladder also. The other is to see a doctor, he/she can run some tests to see if there's something more going with your bladder/kidneys.
The doctor may also try medication to help stop this such as Ditropan.

hmm.. what are the signs of infections, as far as i think.. i doubt i have signs of infection. Could it possibly jus be bad habits? i'm totally stressed out abt it. The day before i even wet my frens' bed. i'm totally embarrassed now.

in addition, i heard medications are just temporary. and i am afraid to go to the doctors cause it may be costly.

Signs of infection can range from strong urine odor, puss in your urine, fever,chills,
burning when urinating, pain in your abdomen and/or kidneys.
Everyone is different with the symptoms they have.
Do you eat a lot chocolate or drink soda, coffee or tea? These things can aggravate the bladder.
Medications are temporary but it might help until a doctor can figure out what is going on.
Yes I agree it can be costly to see a doctor. Do you have health insurance? If not you can look into a clinic that offers free or low cost testing.

What bad habits are referring to you? Stress can also be a culprit.

thanks alot for the constant replies. i do love chocolates, but i dont realli drink coffee or tea. By the way, consuming alcohol,to make me fall into deep sleep does it actually help prevent bed wetting? i feel stress only when staying overnight at my fren's place.. and nope i dun have any health insurance.

oh to add on, the symptoms u mentioned, i dont have any. i feel irritated, i have to use blankets instead of comforters/quilts because wetting them means alot of washing and cleaning to be done. even my mattress are those without springs in them. its a total shame and disgrace. sigh.

I do understand how you feel as this has happened to me for a time also, even into adulthood, but then again I have kidney/urological problems.
I think it would be best if you contacted a doctor to find out what is causing this.
I don't think alcohol will help with bed wetting, it will put you in a deep sleep which only add to the bed wetting.
Take Care
