HK - I am a light weight when it comes to meds. I take 300 mg in the a.m. and 600 mg before bed - a total of 900 mg. A couple of times they had me increase it to 1200 mg a day but I would end up being emotional and crying all the time. So 900 mg is my personal max.

The 300 mg in the a.m. lasts me all day even though Neurontin has a short half life. The 600 mg helps me during the night and seems to keep some of the spasticity from waking me up. (It could just be that 600 mg of Neurontin for me knocks me on my bu**. I take it around 7:00 p.m. and within a couple of hours I start feeling the full effects. Sometimes it's like have a few drinks and becoming more "chatty" than normal. LOL.)

Some people do start to build a resistance to it and need to increase their dosage. I can't remember the maximum amount, but it is a lot higher than what I take.

Definitely talk to your doc about it at your next visit. There may be something that will work better for you.
