That's a low dose of baclofen Danny. I personally have found mine decreased as years went by. I was on about 40 mg a day 15 yrs ago. Now I take 10 mg at night and that's all. I know people that take much more, some have to get a pump implanted in their side because they shake so bad. I would imagine the doc will increase your dosage and hopefully it will help. If it doesn't look for other problems. Im sure you heard my crazy appendix rupture story.......it started with spasms in my stomach.
