I can’t really talk to the T2 with experience though the night time thing sounds like a Somogyi effect where your BG goes too low and then your liver makes a bunch of glucose to compensate. A diabetic friend had that last night and we decided it was because he’d cut his carbs but not his insulin so he went hypo overnight. If you go Keto, consider titrating your insulin down in concert with carb cutting. It seems like the effect of lower carbs on insulin needs is very quick. Verify with others on here who have done this (many stories) and/or doctor if they are Keto friendly.
As for gout… that I can attest to. As you lose weight, toxins are released from adipose tissue and one of the many side effects can be gout. Women can get a flush of estrogen, enough to temporarily reverse menopause, stoners can get years of stored THC and we can get gout. The standard gout advice still applies, water and pills as well as trading out more uric acid producing foods with lower. IMHO, it is a price worth paying and mine did not last as long or as severely as my pre Keto attacks. Short term pain in the toes… or no toes. No brainer?
