Pregabalin tolerance may build quick but it also drops quick, I took pregabs every other day for about 18 months at the same dose and it had consistent positive effects each time, I could tell also if I left it 2 days between dosing, the hit was again stronger.
Now I'm not saying that those days on Pregabalin at the end of that 18 month period were as strong as at the beginning of the period, just that it still had very tangible beneficial effects, unlike anytime when I took it on consecutive days which just rendered it inert until I took at least 1 day off.
Give yourself a full 36 hours off pregabalin and I believe you will notice the difference in a big way. Consecutive days is in my opinion (and I have been on pregabalin daily for maybe 2 years more at a dose of 600mg daily) is a complete and total waste. When you can trust it will work every 48 hour cycle you can at least get through the off day knowing that the following day will be so much easier with the pregabalin regulating your mood and keeping you positive. Also you can plan around any necessary activities that usually trigger you anxieties even if it means you have to take a 2 day break so you can dose the day you will be facing anxiety, which has the added benefit of making that days dosing work even better due to the 2 day abstinence.
I would say that until you can balance your life so that it is manageable without sending you running to additional benzos to regulate your mood and until you achieve this with the medication you are taking, which helps, you have almost no chance of doing this successfully.
Currently you are sometimes taking almost double the usual 30mg dose of benzos just to cope, we can safely assume that the medication helps you navigate your day successfully and doesn't compound the issue by say making your anxiety way more acute, if it did you would have no problem quitting these drugs.
The same stressers that cause you to lean heavily on your medication now will still be there but you will be trying to reduce your supportive medication from a situation where you currently feel.out of control and that is gonna be ultra difficult.
I think until you can stabalise with the dose of medication you are currently taking and manage down the times you are taking loads of benzos on top of the pregabalin you won't be able to move forward, so it is imperative to start taking 1 full day break between dosing pregabalin to give it a chance to actually work in lifting your mood. Once you have had a period of stability and you feel like you can cope day to day without the 50mg benzo days then you can start to look at reducing the pregabalin dose, with a goal of not taking it at all.
I think this is the only way you can successfully quit medication at least stage 2 of a full detox plan if that's what you are aiming for, which is the discontinuation of pregabalin.
Peace and love
