Do roms become unstable after use?

[AC Question]

I have a galaxy s3, rooted. I am running Liquidsmooth rom for almost 8 months.
Just realised that its becoming quite unstable now. Frequent restarts, bad battery and stuff.
The battery has become horrible. It charges 4% per hour!!
Should I revert back to my stock rom or is there something else i can do?

Also, will going back to the stock rom help fix the battery problem?

Can you able to do a soft reset?

Try a factory reset (backup data before hand) and see if that fixes your problem with Liquidsmooth. You may need to restore GAPPS, so make sure you have that file loaded on the sd card. Months of use and downloaded files is likely the problem. If that doesn't help then try a reset and flash the ROM and GAPPS again. Let us know if that helps.

ROMs don't become any more unstable than any other software (and something I wrote in 1978 is still running today, so I wouldn't call software "unstable". The hardware they're running on could develop problems, the environment (which is what the other 2 posts are talking about) can become cluttered with useless data, but if the hardware is still good, the ROM (the term actually refers to a chip, but in cellphone usage it refers to software) won't become unstable.
