The conversation between human and AI assistant.
[|Human|] Hi I have been diabetic T2 for the last 2 years now my med is metformin 500mg per day and I am also taking Prinivil for blood presure 5mg per day-I am now living in Crete Greece originally from UK I have been in crete for 18 months and with the meditereanian diet I have lost about 33 k (i now weigh 13.1/2 stone I am always feeling light headed Numbness arms,legs,feet.hands-yet my blood sugar readings are good- between 108-112 my blood presure is good too but i am always walking around as if i am drunk however it is worse when I am trying to sleep which seems strange as I should be more relaxed. sometimes I feel so light headed laying down that I have to sit up in case I pass out (which i have not done as yet)
[|AI|]  Hi, Your could be related to generalized fatigue, weight loss or due to nutritional deficiencies. Metformin use can cause Vitamin B12 deficiency which can present as fatigue, burning sensation or pins and needle sensation. Regular use of Vitamin b12 tablets should be taken after food. Maintain your weight within the normal body mass index. Your symptoms will reduce in the subsequent days. Take care. Hope I have answered your question. Let me know if I can assist you further.
