wave,

Keep in mind that markneil is 350 pounds. It may be a part of why such a high dose is needed and well tolerated.

I am 150+ pounds and have taken up to 1200 mgs before bed. At first, I needed 1200 or at least 900. Now, I do fine with 600.

It is not know to help with normal pain (that's an off label use), such as skeletal pain but helps some with nerve pain similar to Lyrica.

I've been taking it for 14 years.

I take it to reduce the body jerks and to help my mind let go of thinking. Its half-life is only 8 hours so unless it is taken multiple times during the day, its benefit can be targeted at sleep issues.

markneil, If you are waking up still tired, did you keep your cpap mask on ? Apnea will negate the good sleep benefits.
