It's hard to answer your question because drugs affect people so differently. We metabolize them differently, get different side effects, get different benefits. Our bodies differ in how strong they are -- some people can take a lot of drug and not be affected much and some can't take any because they're so sensitive, and as we age it gets harder and if we're very young it's harder. But this much is true: you're taking three drugs that slow metabolism and can make you tired. You're not taking any drug for depression. You're taking one for anxiety and pain relief (Gabapentin, which is basically the neurotransmitter GABA shot straight to your brain because taking it as a supplement usually doesn't get past the blood/brain barrier) that is known for being very sedating. You're taking one for epilepsy that is used off label sometimes for bipolar, which you don't say you've been diagnosed with (lamotrigrine). I assume your psychiatrist is using this because of a determination you don't respond to antidepressants, although if you've only taken Zoloft and Paxil you've barely scratched the surface of available ones. When they do this they call them atypical antidepressants, meaning they aren't intended for that purpose but some people have responded to them. You're also taking a drug that targets GABA receptors, Klonopin, that is also sedating and is used for anxiety. So, yeah, you're likely to be tired. Those epilepsy drugs, and atypical antidepressants in general, have a lot of side effects. As for the weed, it generally doesn't go well with anxiety -- many people get their anxiety while using it. But for some anxiety sufferers it calms them. It also doesn't go well with depression because it causes introspection and rumination and isolation if you use it a lot. In your case, you're combining it with three other sedating drugs. So again, yeah, you're probably going to be listless and have trouble with sleep and staying awake because all these drugs can interfere with REM sleep. They can all affect memory if used regularly. And they are all downers, which means they can make depression worse. When a recreational drug is not longer Saturday night fun but becomes a lifestyle, it's not longer a drug, it's a maintenance substance just because you don't feel as good when you're not high. Although pot isn't addictive, anything done over and over can be very hard to stop doing. The good thing is, there's no withdrawal, as there probably will be when you stop the prescription meds you're taking. You can just quit. I did, when I started getting anxiety attacks when I was stoned. It's actually easy. The only problem is, you'll miss being high, but it's better to be healthy, no? Anyway, I have no idea what road you've been down, but you are combining drugs with similar bad side effects and it sounds like they're building up. You don't mention having tried therapy before going down the drug route. You don't say how good a trial you gave Zoloft, and if Paxil was the first drug you were tried on, I'm thinking you don't have the best psychiatrist, assuming you're using one at all. You know better than us how you got here, and there could be great reasons for it, but I hope you get a good sense of what these drugs are for, how they work, and what the downsides are so you can participate in your care. But the first thing to do is, stop the pot. It's easy. Really. Don't just quit the other drugs. They can be hard and need to be done slowly and safely.
I'm sorry, I forgot to mention I'm on 2mg klonopin spread through the day. Memory see..
