Injections due to sugar levls aftr covid

Got covid positive on 30th of August 2020 and taken treatment for a week and told rest for 2 months and started facing fluctuations in sugar levels and using insulin and injections but still not getting into control and increased dose of insulin to 30 morning and 20 night and using VOG LOW-GM2 (glimepride) twice a day daily and hyderoxyzine hydrochloride twice a day for 7 days and Multivitamin tabels. I am also having High BP and using Amlosafe (Amlodipine, Telmisartan & Hydrochlorothiazide Bilayer Tabels) Now I am still feeling problem with infections or something which occurs wounds across entire body mostly on lower body in between legs and on legs and on neck. Do I need to take any extra medicines for this or do I need to consult any specialist? And can he take alchohol on regular basis or irregular basis. Kindly suggest me on this.
