I thought I'd report back on some of my observations taking Baclofen, as well as opioids.
To my dismay some of the symptoms I'd thought would be helped by the Baclofen, PEM and post-reading malaise, were untouched or even exacerbated at high doses of the drug. I'd theorized that these symptoms would improve based on my response to GBL, also a GABA-B agonist. So the reasoning was these symptoms could be ameliorated by addressing the underlying excitotoxicity.
I slowly worked my Baclofen dose up to 320 mg/day and this was certainly too much. I experienced erratic moods, falling asleep through the day and waking up at night. There was also a worsening of my post-reading malaise. So I dropped the dose down to 240 mg and am comfortable without any of these nasty effects. In fact I'm enjoying improvements.
The drug, as expected, combats excitotoxicity. As a result I've more mental energy and a clearer head. I feel calmer, more motivated and am getting a lot done. My mood and libido are also elevated. The severity of my fasciculations has been cut in half. However what I find most interesting is the effect it’s had on my sleep schedule. I've actually fallen effortlessly into a normal circadian rhythm. I'm hardly able to keep my eyes open after eleven o'clock, and then I wake up between 6 and 7 the next morning.
So the symptoms I was hoping would be treated with the Baclofen are actually responding better to opiates. The major difference between GBL and Baclofen, besides the half-life, is the effect on endorphins. Baclofen is very specific to the GABA-B receptor, while GBL has a high to it. It turns out if I pop an Oxy or a Statex I'm able to read or engage in physical activity that would have been beyond my capabilities without developing PEM. To the point I can actually workout a little. I've no idea how far I can push this as, like everyone here, I've been conditioned by horrible crashes in the past. Though this is something I'm going to have to test further.
I find I'm even better the next two days after my opiate dose. This is similar to what Tristen describes. I believe the benefit is especially pronounced in combination with the Baclofen. At times it’s like my brain just lights up and I don't feel sick anymore! It's very encouraging. I'm thinking I'll start with LDN. If that doesn't work I'll try full dose Naltrexone. If that doesn't get me there I'll try a modest dose of Suboxone, etc, until I find something that works.
